An INTERLOCK serves as an OFF-ON switch. Because of its
design, the INTERLOCK provides additional functions.
First, it removes the power from the unit when an
operator opens a panel or drawer.
This provides safety
for the operator. Secondly, when testing is required by
the repair person, it restores power to the unit when
placed in its most forward position.
