Knife Switch

Knife Switch: 

It is a type of switch used to control the flow of electricity in a circuit.

It is composed of a hinge which allows a metal lever, or knife

to be lifted from or inserted into a slot or jaw.

The hinge and jaw 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 jaw.

Knife switches can take several forms, including 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.

Specifications:

• Low voltage, may be used as changeover switch with appropriate connections.
• moulded base with plated spring metal contacts and screw connectors.
