Magnasphere Corp MSS-301C-WG-GREY Recessed Contact Switch

Product Description

The MAGNASPHERE CORP MSS-301C-WG-GREY is a recessed contact switch designed for use in security and access control wiring applications. This single-unit device features one recessed switch with one closed loop configuration, making it suitable for monitoring the open and closed status of doors, windows, hatches, and similar entry points. Electricians and security system installers work with recessed contacts like this one to provide a clean, concealed installation that is less visible and more tamper-resistant than surface-mounted alternatives. The recessed form factor allows the switch to be embedded directly into the door frame or mounting surface.

This contact switch is used in residential and light commercial security installations where a low-profile, in-frame mounting solution is required. The single closed loop configuration is compatible with standard alarm panel zones and access control inputs that monitor circuit continuity. It is sold as a single unit and is well suited for new construction rough-in work as well as retrofit projects where concealed wiring is preferred.

Installation Notes

Installation is typically performed by a licensed electrician or certified security system technician. Power down and disarm the alarm panel or access control system before wiring this contact to any zone input. Drill the recessed pocket to the manufacturer-specified diameter and depth to ensure proper seating and reliable reed switch actuation. Follow local electrical codes and any applicable security industry wiring standards during installation.
