GKLE46LXA2 -HONEYWELL - Keylock Switches SAFETY
DESCRIPTION
MICRO SWITCH GKL/R Series switches are a heavy-duty key
operated solenoid safety interlock switch incorporating a key
trapping mechanism. The trapped key attached to the guard
cannot be removed from the switch until the solenoid circuit of
the switch has received a remote signal (from a control device)
indicating the hazardous process has subsided. This design is
for use on machinery where an instant stop is either impossible
(due to the momentum of the machine) or impractical due to
machine conditions (such as completing a machine cycle or
reducing the temperature to a safe level). There are independent
contacts inside the key switch which monitor the key position
and the solenoid with a range of different contact arrangements
to satisfy most application requirements. All normally closed
contacts of the switch are positive opening . The key switch
also incorporates a manual override feature on the front cover
which allows removal of the key for emergency access.
To facilitate installation, the switch is available as a GKL Series
(head to the left) or a GKR Series (head to the right). The GKL/R
Series switches are designed with dual-entry positions (side or
top) for the key.
