SAFETY SWITCHES
GSS Series
Hinge Mount Safety
Limit Switch
80
The Hinge Mount Safety Limit Switch is designed for use on machine access doors as an alternative solution
to key operated interlocks and safety limit switches. When the access door is opened, a follower pin (not
supplied) slides down the slot in the actuator lever, forcing the actuator lever to rotate and positively open the
NC safety circuit to shut off the machine. Closing the access door rotates the actuator lever to the reset
position, closing the NC safety contacts.
The Hinge Mount Safety Limit Switch minimizes alignment problems because it may be offset-mounted from
the hinge point of the door. The tamper-resistant design and the positive opening contacts provide a higher
level of safety than the conventional spring-driven limit switches often used to monitor door position.
Low Energy Switching
In today’s demanding age of low energy controls, electromechanical switches are frequently used to interface
directly with safety relays, PLCs and other low energy devices. To accommodate this requirement GSS offers
a new gold plated contact version of the standard basic switch. This improves reliability of switching at low
currents and voltages by protecting the contact surfaces from contamination during operation or storage
prior to use.
Standard silver contacts have a disadvantage in that the contact surface may tarnish under certain
environmental conditions, e.g. in the presence of moisture.
Low energy basic switches are rated as follows:
Operating Voltage U
Operating Current I

Switching options:
Snap action contacts (1NC/1NO)
Slow action contacts (1NC/1NO) BBM
