Camden Door Controls CM-1100 Key Switch Spst Momentary N/o

Product Description

The Camden Door Controls CM-1100 is a single-pole single-throw (SPST) momentary key switch configured normally open, designed for access control and door activation applications. When the key is inserted and turned, the switch momentarily closes the circuit to trigger a connected device such as an electric door operator, magnetic lock release, or access control panel. The switch returns to its open state when the key is released. This type of key switch is a standard component in commercial and light industrial door control systems and is typically installed by low-voltage electricians or security systems integrators.

The CM-1100 is suited for use in commercial entryways, controlled-access doors, and building security systems where a keyed input is required to actuate a door operator or release a locking device. It is commonly mounted in standard electrical boxes at entry points including lobbies, parking garages, and secured corridors. The momentary normally open configuration makes it compatible with door operators and access panels that require a brief contact closure to initiate an action.

Key Features

• SPST momentary circuit action returns switch to normally open state upon key release
• Keyed operation restricts unauthorized activation of connected door or access control hardware
• Designed for low-voltage access control and door operator circuits
• Compact form factor suitable for standard electrical box mounting
• Sold as a single unit (each)

Compatibility

Designed as an OEM-style key switch for commercial access control and door operator systems requiring a momentary normally open SPST input. Refer to the CM-1100 product data sheet for detailed wiring and compatibility information.

Installation Notes

Installation is typically performed by a licensed low-voltage electrician or certified security systems integrator. De-energize the access control panel and any connected door operator before wiring the switch. Follow NEC guidelines for low-voltage wiring and observe local building and fire codes when mounting key switches at controlled-access entry points. Verify that the circuit voltage and current rating of the connected load do not exceed the switch rating before commissioning.
