This is a solenoid-interlock safety switch used to guard access to hazardous areas of machinery, holding a guard door closed until the machine has reached a safe condition. Rated at 250V with a 10W solenoid consumption, it is typically wired into a safety circuit that releases the interlock once the associated process or motion has stopped. It is used on panels and machine guards where access must be electrically controlled rather than left to a simple mechanical latch.
