Technical distinctions between selector switches and push buttons
ONPOW Push Button Manufacture Co., Ltd. has outlined the fundamental operational differences and specific use cases for industrial control switches.

In the design of industrial control panels and automation systems, the selection of input devices is critical to operational safety and efficiency. While both selector switches and push buttons are essential for machine control, they serve distinct functional roles.
A selector switch is primarily designed to choose between various operating modes, such as manual, automatic, or off. By maintaining a selected position, it provides clear visual feedback on the current machine state. In contrast, a push button is an actuator designed to trigger a discrete, specific action—such as initiating a start sequence, executing an emergency stop, or resetting an alarm.
The effectiveness of these components in a control circuit relies on the specific contact configuration and wiring setup. Engineers must select components based on whether the application requires a persistent state setting or a momentary control input. Proper selection ensures clear operator interface and functional reliability across production machinery and electrical enclosures.
