GKS Series
Multi-Entry Trapped Key-Operated
Safety Interlock Switch
DESCRIPTION
The introduction of the GKS product marks a significant new
product class for Honeywell. Honeywell’s switching expertise
has been applied to a cost-effective, trapped key safety
interlock switch. This product allows OEMs to hold a door or
gate closed while a hazard still exists. This is particularly
important where there is momentum in the machine. In other
words, when the machine is signaled to stop, the momentum in

FEATURES
Global approvals (CE, cULus, CE, and CCC)
Glass-filled polyester body
Power-to-lock and power-to-unlock schemes for key trap
Flexible switching arrangement
24 Vdc, 110 Vac, and 230 Vac coil voltages
Over-ride mechanism in cover
Head may be rotated into 4 different positions
Three conduit openings (knock-out style)
Switch position provides status
the machine can mean that parts of the machine are still
moving and pose an injury risk if the access gate or door is not
held closed. Global approvals and standards are important to
Honeywell’s customers; therefore, the GKS product conform to
the requirements of IEC60947-5-1 and carries cULus, CE and
CCC approvals.
BENEFITS
Product may be applied to most applications worldwide
Tough, cost-effective, double-insulated enclosure
Choice of key trapping methodology
Four contacts that can be arranged in any configuration1
Multiple voltages provide for every geography

product combinations will depend on the popularity of that type. Please check with your local distributor or Honeywell
representative for the available types in your region.
LED OPTION
The built-in LED is suitable for direct installation in the M20 x
1.5/0.5 in NPT thread, one of the three cable entries in the
GKS safety switch. The built-in LED can indicate to the user
whether the solenoid is unlocked/locked or whether the door is
open/closed. The switching element can be wired individually.

CIRCUIT AND TRAVEL DIAGRAMS
NOTE: This ‘truth table’ shows the switch status in various
conditions. In each column, there is a change in switch contact
position from the previous column. It is possible to determine
the status of the switch by examining the combination against
the table. This can be essential for operational reasons. For
instance, the machine should not be started until the key is not
only in the head, but is also trapped.
The first column depicts the key inserted and the key trapped
in that position – this would be the typical run position for the
machine – all doors closed. The second column illustrates the
key inserted, but not trapped – this would be the safe-to-open
the door position (as determined by the application’s safety
scheme). The third column shows the key extracted or dooropen position.
