Camden CM-1000/31 SPST Momentary Contact Switch

Overview

The Camden CM-1000/31 is a Single Pole Single Throw (SPST) momentary contact switch rated 15 amperes at 30VDC, engineered for access control and door strike circuits where reliable, heavy-duty switching is non-negotiable. This normally open (N/O) switch mounts in a 1/4-inch thick cast aluminum enclosure and accepts standard 1-inch to 1-1/4-inch mortise cylinders, making it suitable for wall, pipe, or pedestal installation in indoor or outdoor environments. The CM-1000/31 solves the integration problem: you need a keyed switch that doesn't require external power logic, doesn't introduce network latency, and won't fail under high-frequency activation cycles typical of electric strike or electromagnetic lock control.

Compatibility

The CM-1000/31 integrates with any door strike, electromagnetic lock, or motor circuit rated for 30VDC operation up to 15 amperes. Compatible with standard mortise cylinders (1", 1-1/8", 1-1/4") and works in both legacy hardwired access control panels and modern networked systems via a relay interface. The momentary contact output is protocol-agnostic—connect the soldered 18 AWG color-coded leads directly to a strike control module, relay coil, or auxiliary input on a networked access controller.

Installation Notes

The housing features a weather-resistant surface mount box with heavy-duty rubber gasket suitable for outdoor exposure. No set screws required—locators prevent cylinder spin. Installation includes tamper-proof screws and driver. The cast center rib protects internal switches from mechanical shock. Heat-shrink protective sleeves cover contacts, and color-coded leads simplify wiring. Brushed aluminum finish resists corrosion; custom color finishes and engraving are available through the manufacturer.
