Frequently asked questions

What are Single-Phase Motor Starting Switches and where are they used?

Single-phase motor starting switches are cam switches used to start single-phase motors with an auxiliary (starting) winding. After the run position, a spring-return START position briefly connects the auxiliary winding; when released, the motor continues to run on the main winding.

What should I compare when choosing Single-Phase Motor Starting Switches?

When choosing a switch, compare the motor current with the switch's thermal current and motor power ratings, and select the front plate size to suit the mounting space on the panel door.
