A push button switch may be one of the smallest components on a control panel, but it is also one of the components operators use most often.

Start. Stop. Reset. Manual control.

These simple actions need a switch that is easy to install, easy to recognize and dependable during repeated operation.

With this in mind, RY-ELE introduces the RY22SA3S standard illuminated push button switch.

Designed around a 22mm panel mounting format, the RY22SA3S combines push-in wiring, LED indication, multiple contact configurations and IP65 protection in one compact industrial push button. The design focuses on the details that matter during actual panel assembly and daily machine operation.

What Is the RY22SA3S?

The RY22SA3S is a standard 22mm illuminated push button switch developed for industrial control panels and machine operator interfaces.

The switch uses a 22.2mm panel cut-out, making it suitable for conventional 22mm panel applications. Its standard flat-button design provides a straightforward operator interface without taking up unnecessary panel space.

Depending on the selected configuration, the RY22SA3S can be supplied with different contact combinations, including:

• 1NO
• 1NC
• 1NO + 1NC
• 2NO
• 2NC

This allows the same product platform to be used for different control functions and circuit requirements.

Push-In Wiring for Faster Panel Assembly

One of the main features of the RY22SA3S is its push-in wiring structure.

Instead of tightening a conventional terminal screw every time a wire is connected, the conductor can be inserted directly into the terminal. For stranded wire, the spring terminal can first be opened before inserting the conductor. Hard wire or an appropriate crimp terminal can be inserted directly.

When the wire needs to be removed, the release mechanism can be operated with a screwdriver.

The basic operation is simple:

Open → Insert → Release → Locked

This may sound like a small change, but it becomes more meaningful when a panel contains many control switches.

For OEM manufacturers and control-panel builders, reducing repeated screw-tightening operations can help make assembly more efficient and consistent.

Why Push-In Wiring Is Useful for Industrial Control

Traditional screw terminals are still widely used in industrial electrical equipment.

They are familiar, but installation requires manual tightening for every connection.

With push-in wiring, the installer can reduce the number of repetitive operations involved in connecting the switch.

This can be useful when:

• Building control cabinets in batches
• Wiring multiple operator buttons
• Carrying out machine assembly
• Replacing components during maintenance
• Working in limited installation spaces

The RY22SA3S supports applicable conductors and pin-type crimp terminals up to 2mm² according to its wiring specifications.

For production environments, the benefit is less about one individual connection and more about the accumulated time saved across an entire control panel.

Integrated LED Indication for Clearer Operator Feedback

The RY22SA3S is an illuminated push button switch, meaning the button can provide both physical control and visual indication.

Available button illumination colors include:

• Red
• Green
• Blue
• Yellow
• White

LED voltage options include 9–24V and 220V, while other voltage requirements can be customized. The LED is specified for a service life of at least 50,000 hours under the stated conditions.

This makes the RY22SA3S suitable for control interfaces where the operator needs a quick visual indication.

For example:

Green — machine running or ready

Red — stop, fault or alarm

Yellow — warning or attention

Blue — auxiliary or special function

The actual color assignment can be defined according to the machine's control logic.

Multiple Contact Options for Different Control Circuits

Industrial machines do not all use the same control logic.

Some buttons only need a normally open contact. Others may require both normally open and normally closed contacts.

The RY22SA3S provides several contact configurations, allowing engineers to select a suitable version for the circuit rather than redesigning the entire operator interface.

Typical functions include:

Start

A normally open contact can be used to send a start command to a control circuit.

Stop

A normally closed contact can be used within appropriate stop-control logic.

Reset

The button can provide a momentary reset input to a PLC or control circuit.

Manual Control

Operators can use the switch for manual machine operation or auxiliary control.

Signal Control

The contact output can also be integrated into a monitoring or interlocking circuit, subject to the electrical ratings of the selected configuration.

The available contact combinations are defined in the RY22SA3S model selection system.

IP65 and IK08 Protection for Industrial Environments

A control button installed on industrial equipment may encounter dust, water splashes and mechanical impact during normal operation.

The RY22SA3S is designed with IP65 protection and IK08 impact resistance under the specified test conditions.

The product specification also lists engineering materials and sealing components designed for the switch construction, including flame-retardant PA66, PC and NBR sealing materials.

This makes the RY22SA3S a practical option for industrial operator interfaces where basic protection against dust, water ingress and mechanical impact is required.

Built for Repeated Operation

A push button on a production machine may be pressed thousands of times over its service life.

The RY22SA3S has been evaluated for electrical and mechanical endurance under specified test conditions.

Its documented electrical life includes:

• AC230V/10A resistive load: 50,000 operations
• AC120V/10A resistive load: 100,000 operations
• DC24V/10A: 100,000 operations
• Self-resetting mechanical life: up to 10 million operations under the specified test reference

These figures are test values rather than a guarantee of identical service life in every application. Actual performance depends on the load, voltage, current, switching frequency and operating environment.

For engineers, this distinction matters when selecting a push button for a real machine.

Designed Around a Familiar 22mm Panel Format

For machine builders, changing the panel cut-out can create unnecessary design work.

The RY22SA3S uses a 22.2mm mounting hole, with the product designed around a 22mm panel interface.

This makes it suitable for applications where a standard 22mm push button format is already being used.

Potential applications include:

• Industrial control panels
• Machine tools
• Packaging machinery
• Production equipment
• Automation systems
• Electrical control cabinets
• Material handling equipment
• Operator control stations

The product can therefore fit into a wide range of industrial control interfaces without requiring an unusual mounting arrangement.

RY22SA3S for Machine Builders and Panel Manufacturers

For an individual user, the difference between one wiring method and another may not seem significant.

For a machine manufacturer producing hundreds of control panels, it is a different calculation.

A push button is installed, wired, tested and eventually maintained on every machine.

Features such as:

• Push-in wiring
• Standard 22mm mounting
• Multiple contact configurations
• LED indication
• IP65 protection
• IK08 impact resistance

can make the product easier to integrate into a standardized control-panel design.

This is where the RY22SA3S is positioned: not as an overly complicated control component, but as a practical industrial push button designed around everyday installation requirements.

Where Can the RY22SA3S Be Used?

The RY22SA3S can be considered for a variety of industrial control applications.

More Than a Push Button: A Practical Control Interface

The purpose of the RY22SA3S is not to add unnecessary complexity to a machine.

It is about making several small things work better together.

The installer gets a simpler wiring method.

The engineer gets several contact and LED options.

The panel designer gets a standard 22mm mounting format.

The operator gets a visible and easy-to-use control button.

And the maintenance technician gets a switch that can be disconnected and replaced without dealing with conventional screw-terminal wiring.
