HG-1 Door Interlock
For Use With Stationary Cam
The HG-1, electrical/mechanical contact switch
is intended for use with single sliding vertical
rise elevator hoistway doors. It is wired in series
with all the other door switches in the hoistway
and the electrical control circuit of the elevator so
as to produce an overall electrical safety loop. In
addition to this circuit closing system, there is a
mechanical latch which locks the door in the
closed position when the car has started to leave
the floor. The HG-1 interlock has a single
contact and is used with a stationary cam.
The HG-1 is made for right-hand or left-hand
mounting. The hand is determined by standing
inside the elevator looking out. The side on
which the lock is to be mounted (left or right) is
the hand to be ordered.
