CH6, SH6 are switches with connection cables, automatically resetting, with Expoxy

 

CRH, SRH self-retaining with voltage. After the contact is opened, the parallel-connected ceramic resistor heats up and keeps the contact open until the voltage is removed.

 

SH6, SRH fully insulated with Mylar®-Nomex®-cap
