Alarm Controls Corporation MCK-4 Spdt Momentary Push Button Plate

Product Description

The ALARM CONTROLS CORPORATION MCK-4 is a single-gang stainless steel plate assembly fitted with one 4-amp single-pole double-throw (SPDT) momentary push button. It is designed for access control and door release applications, providing a clean, durable switching point at entry and egress locations. The momentary action means the circuit activates only while the button is held, making it well suited for electric strike and magnetic lock release circuits. Licensed electricians and low-voltage access control technicians are the primary installers of this device.

The MCK-4 is used in commercial and light industrial access control systems, typically mounted at doors, gates, or secured entry points where a wall-mounted momentary switch is needed to release an electric locking device. It fits standard single-gang electrical boxes and is appropriate for new construction and retrofit installations alike. Its stainless steel finish suits high-traffic environments where durability and appearance both matter.

Key Features

• Single-gang stainless steel plate for durable, corrosion-resistant surface mounting
• One SPDT momentary push button rated at 4 amps for compatibility with common door release circuits
• Momentary action provides momentary circuit closure, preventing unintended sustained activation
• SPDT switching allows normally open or normally closed wiring configurations
• Compact single-gang form factor fits standard electrical boxes

Compatibility

Designed as an OEM-style replacement or new-installation component for single-gang access control button applications using SPDT momentary switching in electric strike, magnetic lock, or door release control circuits.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage access control technician in accordance with applicable NEC requirements. De-energize the access control panel and any connected door hardware before wiring. Confirm the load current of the connected locking device does not exceed the 4-amp switch rating. Secure the plate firmly to a standard single-gang electrical box before restoring power.
