Door Interlock Switches
DESCRIPTION
Door interlock switches are
attached to the door of
equipment where it is
necessary to turn power on or
off when the door is closed or
opened. This type of control is
used in applications where
maintenance and testing must
be performed inside a cabinet.
Interlock switches are supplied
with one 1PDT snap action
switch or two 1PDT miniature
snap action switches.
The snap action switches are
mounted in a frame and a
single actuator, which is spring
loaded, operates the switch.
When mounted in a door, the
closing of the door forces the
actuator against the spring
thereby closing the switch.
When the door is open, the
actuator springs out thereby
opening the power circuit.
