Product description

The Siemens 3SU1100-1BA20-3CA0 is a 22mm round, plastic mushroom pushbutton with a 40mm diameter head. This actuator is designed for latching operation, requiring a pull-to-unlatch mechanism to reset. It features one normally closed (NC) contact and utilizes spring-type terminals for quick and reliable connections.

This pushbutton is ideal for applications requiring a distinct visual indicator and a latching function, such as machine start/stop controls or emergency stop functions where a manual reset is needed. The large mushroom head allows for easy actuation.
