Knife Switches

Knife Switches offered in a heavy duty rugged design. Front connected units with molded handles and insulated bases, available in either Type A or Type B style.

Knife Switches are a type of switch used to control the flow of electricity in a circuit. It is composed of a hinge which allows a knife to be lifted from or inserted into a slot. The hinge and slot are both fixed to an insulated base, and the knife has an insulated handle to grip at one end. Current flows through the switch when the knife is pushed into the slot.

These units are either single throw, in which the “knife” engages with only a single slot, and double throw in which the knife hinge is placed between two slots and can engage with either one.
