When a buyer is buying push button switches in bulk, the question is how to find a supplier who can provide consistent product quality, dependable electrical operation and dependable and long term supply rather than the lowest unit price.
But what can you do to evaluate a push button switch manufacturer before ordering? The following guide will give an extensive overview of the key criteria that should be considered, including the product specifications, the quality of the materials used, safety certifications, customization, quality control, and production capacity. It also contains details on the questions you ought to enquire of the prospective suppliers and the red flags to watch out which will help you to make a sourcing decision.
The first thing you have to decide is if a manufacturer provides push button switches that can satisfy your equipment needs. Various designs, electrical ratings, mounting sizes and operating functions are required for various applications.
A reputable push button switch manufacturer should be able to communicate product specifications to the buyer, and assist in determining which product is appropriate for their use.
The most frequently used push-button switches are:
➤ Momentary push button switches: Turn a circuit on/off when the button is pushed, most commonly in start and stop uses.
➤ Latching push button switches: Stay in the operating condition until another push is made or reset.
➤ Illuminated push button switches: A light may be added to indicate the operating condition or for greater visibility.
➤ Emergency stop switches: These switches are used as emergency stops.
➤ Selector and multifunction control switches: Assist in performing certain control functions in industrial equipment or electrical panels.
When comparing products, consider rated voltage and current, contact configuration, mounting diameter, terminal type, mechanical and electrical life and environmental protection rating.
When deciding on a push button switch supplier, one of the most critical criteria is the quality of the product. Inconsistent actuation, wear of contacts, broken switch casings and faulty electrical connections are all potential issues with poorly-made switches.
These issues can lead to higher maintenance demands and performance issues with installed equipment.
If you are considering a manufacturer, consider the following:
▪ Housing and actuator materials: The case material needs to be strong enough to withstand the mechanical requirements of the application, and resistant to environmental conditions. Metal and engineering plastic housings have differing properties and characteristics with respect to impact resistance, weight, appearance and operating conditions.
▪ Internal contacts: Contact materials and construction affect electrical conductivity, contact resistance and wear under switching loads. The buyer must make sure the contact system is capable of the voltage, current and load type specified.
▪ Spring and operating mechanism: The internal mechanism should offer consistent operation and repeatability of return or latching as per the design of the switch.
▪ Terminals and connections: Secure connections reduce the possibility of loose wiring, overheating and intermittent electrical contact.
Don't take product photos or product statements for granted, get technical data sheets and test data from the manufacturer.
Not all push button switches can be used in all electrical applications. Buying a product because of its looks or size may cause compatibility issues.
When considering a push button switch manufacturer, ensure that the product they offer is suitable for the electrical and mechanical specifications of your system.
Important specifications include:
○ Rated operating voltage and current
○ Contact configuration, such as normally open (NO) or normally closed (NC)
○ AC or DC operating conditions
○ Resistive, inductive, or other applicable load characteristics
○ Insulation and dielectric performance
○ Mechanical and electrical endurance ratings
○ Ingress protection (IP) rating, when required
○ Applicable product safety and regulatory requirements
It's also crucial to keep in mind that the electrical rating of the switch is different from the rating of the entire control system. A switch designed to operate under a specific resistive load might not be compatible with the same current when used under all inductive or high inrush circumstances.
In the case of emergency stop applications, the switch must be suitable for the safety function it is intended to perform and must be part of a suitable safety circuit.
Request suppliers to provide the appropriate test reports, declarations or certification documents for the product model.
Although standard push button switches might be suitable for many applications, OEM equipment manufacturers might need particular size, color, lighting, terminal settings, or branding.
An efficient push button switch manufacturer must be able to inform you about the possible customization and how it will affect the product, lead times and price.
Depending on the product range, customization may include:
◇ Different actuator colors and shapes
◇ Illuminated buttons and LED options
◇ Alternative mounting dimensions
◇ Different contact configurations
◇ Screw, push-in or other terminal arrangements
◇ Customized markings, symbols, or branding
◇ Product configurations for specific control panel layouts
Technical support is also crucial. Before making production, a supplier should be able to read your specifications and inform you that there may be a problem with compatibility, and be able to offer the correct drawings and specifications.
For instance, when designing a small control panel, a slim push button switch might be useful in saving installation space. But the chosen model still has to meet electrical ratings, wiring needs, mechanical limitations, etc.
When ordering in bulk, order samples if possible. Check the installation fit, operating feel, electrical characteristics and compatibility with the existing design of the intended equipment by testing the switches.
Consistent quality of successive production runs is as significant to buyers as the performance of a particular sample.
A push button switch supplier should have a set of procedures in place for the inspection of incoming materials, the control of the assembly process and the verification of the finished product. These processes can be used to detect defects prior to shipment.
Here are some questions to ask when evaluating a manufacturer's production capacity:
? Does the manufacturer have documented inspection procedures?
? Are electrical and mechanical performance tests conducted as appropriate?
? How are defective products identified and handled?
? Can production batches be traced when necessary?
? Are inspection records available for relevant orders?
? How are design changes and product revisions controlled?
Depending on the product and the application, appropriate tests can be conducted such as contact continuity, operating force, illumination function, dielectric strength, ingress protection, endurance testing, etc.
Don't presume that all manufacturers conduct all tests. Inquire about the tests used for the product being purchased, and whether they can be documented.
Price is one of the major factors to consider when buying push button switches in bulk; however, the lowest quoted price doesn't necessarily mean lowest overall cost.
A lower cost switch might need to be replaced more often, or add more work to maintenance, or have compatibility issues when installed. These expenses can offset the initial savings.
When you are comparing quotations from numerous push button switch manufacturers, you need to take into account:
● Purchase price: Compare the prices of the same order quantity and of the same specifications.
● Installation Costs: Check the mounting dimensions, available wiring options and compatibility with your equipment.
● Maintenance/ replacement: Examine relevant endurance data, operating requirements and expected maintenance/ replacement requirements.
● Shipping expenses and delivery times: Assess shipping, packaging, reliability of delivery and inventory planning.
● Warranty and technical support: Familiarize yourself with the warranty conditions, how the defect should be handled and the reaction of the supplier.
A good push button switch supplier will keep the client fully informed, starting with the first inquiry up to the repeat orders.
Before deciding on the supplier, take time to evaluate their capability to respond to technical questions, provide estimates, confirm specifications and provide lead times.
A professional supplier must be able to explain:
➤ Minimum order quantities and sample availability
➤ Standard and customized product lead times
➤ Packaging and shipping arrangements
➤ Documentation supplied with the order
➤ Procedures for handling quality issues
➤ Availability of technical assistance after delivery
It is particularly critical to communicate with international buyers in the case of customized products or several product models. Documentation helps minimize the chance of ordering the wrong configuration and keeps purchasing/engineering and quality teams on the same page.
Whether the supplier provides other related electrical control components should also be taken into consideration. You might find it easier to purchase the compatible components through a trusted supplier, as long as they all have the necessary specifications.
