Camden Door Controls CM-7020R/3 Momentary Push Button

Product Description

The Camden Door Controls CM-7020R/3 is a momentary push button switch with spring return action and dual-contact output, providing both normally open (NO) and normally closed (NC) configurations in a single unit. Designed for access control and door activation applications, this push button is a staple component in commercial and institutional entry systems. Electricians and low-voltage security technicians install this device as part of exit device circuits, door release systems, and automatic door operator setups. The spring return mechanism ensures the contacts reset immediately upon release, making it suitable for momentary-trigger logic in access panels and control boards.

The CM-7020R/3 is used in commercial door control applications where a reliable momentary switching device is required. Common installations include electric strike and magnetic lock release circuits, automatic door opener call stations, and egress push button stations. The dual NO/NC contact output gives installers flexibility to wire for either a normally open or normally closed control loop without requiring additional hardware. This device is sold individually as a single unit.

Key Features

• Momentary action with spring return — contacts reset immediately on release
• Dual-contact output: both normally open (NO) and normally closed (NC) available
• Single-unit packaging — sold per each
• Suited for exit device circuits, door release systems, and access control panels

Compatibility

Designed as an OEM-style replacement or new-installation push button for commercial exit device and access control systems requiring a momentary, spring-return NO/NC switch.

Installation Notes

Installation is typically performed by a licensed electrician or low-voltage access control technician. De-energize the door control circuit and any connected electric hardware before wiring. Follow all applicable NEC guidelines for low-voltage control wiring and local AHJ requirements for egress and access control devices. Verify contact configuration (NO or NC) matches the logic requirements of the connected control board before commissioning.
