The RY-ELE SA2 Screw-In Series is a range of 22mm industrial push button switches developed for applications that require secure terminal connections and higher current capacity. Its traditional screw-clamp wiring structure provides strong conductor retention, making it a practical choice for machinery exposed to vibration or for projects where technicians prefer conventional wiring methods.

With selected models rated up to 25A, the SA2 Series can meet a variety of equipment-control requirements. Available options include flat push buttons, transparent illuminated buttons, emergency stop switches, rotary selector switches, key-operated switches and LED indicators. Both metal and plastic heads are offered to suit different cabinet designs, operating conditions and purchasing budgets.

The modular contact structure supports different normally open and normally closed combinations, allowing engineers to configure circuits for start/stop commands, safety shutdown, manual/automatic mode selection, equipment authorization and operating-status indication. Illuminated versions provide clear visual feedback, helping operators identify machine conditions quickly.

SA2 screw-terminal push button switches are suitable for industrial machinery, motor control panels, packaging equipment, production lines, HVAC systems, elevators, pumps, compressors and power distribution cabinets. Standard 22mm mounting dimensions also simplify panel design and product replacement.

RY-ELE supplies the SA2 Series to OEM equipment manufacturers, control panel builders, automation contractors and electrical distributors. Multiple colors, contact arrangements, voltage options and customized markings are available, with support for samples, bulk procurement and OEM/ODM projects.
