Interlock Switches

Guard Locking Switches

Spartan

Description

The Spartan is a positive mode, tongue operated guard locking

interlock switch that locks a machine guard closed until power is

isolated and ensures that it remains isolated while the guard is open.

It is available in two contact configurations: two safety (N.C.)

contacts and one auxiliary (N.O.) contact or three safety (N.C.)

contacts. The Spartan head has two entry slots and it can be rotated

to provide four actuator entry points. A blanking plug is provided to

seal the unused slot.

The guard may only be opened when a signal is applied to the

Spartan’s internal solenoid which releases the lock mechanism.

Therefore the Spartan is ideal for machines which do not stop

immediately or where premature interruption of the machine could

cause damage to tooling and components or cause an additional

hazard.

The locking mechanism withstands forces up to of 1200N (270lbs.)

and an LED provides visual indication of switch status.

A catch kit with actuator alignment is also supplied to relieve stress

on the locking solenoid and to protect the unit from actuator

damage due to poor guard alignment. Manual release points with

security screws or special key allow the locked Spartan to be released

in the event of total power failure on a machine.

Features

•Power to release

• Lid mounted status indication

• High locking force—1200N (270lbs.)

• 2 N.C. & 1 N.O. or 3 N.C.

• Rotatable head: 4 possible key entry slots

Typical Applications

Note: Lift-off guards require good alignment when using

tongue actuated interlock switches.

IMPORTANT: It must not be possible to lift the guard

without actuating the interlock. An interlock on either side

may be required.
