Momentary Key Switch Operation

The CS-452 uses momentary switch operation, meaning the electrical contact is activated only while the key is turned to the operating position.

When the key is released, the switch returns to its normal position.

This makes the CS-452 well suited for functions such as:

• Momentary door release

• Remote reset

• Authorized system control

• Electric lock release

• Delayed-egress control

• Access-control signaling

• Electrified exit-device operation

Actual switch and LED functions depend on the wiring and connected control system.

Dual LED Indicators

Two integrated LEDs provide clear visual indication at the keyswitch:

• Green LED

• Red LED

The LEDs can be wired to display system conditions such as door, lock, alarm, or access-control status depending on the application and controller configuration.

Common Applications

• Detex delayed-egress systems

• Electrified exit devices

• Access-control systems

• Electric locks
