Magnasphere Corp MSS-19C-W Recessed Magnetic Contact Switch

Product Description

The MAGNASPHERE CORP MSS-19C-W is a 3/4 inch recessed magnetic contact switch designed for open loop security and access control circuit applications. The unit ships with leads attached and is finished in white to blend with standard door and window frame installations. This type of special-application contact is installed by security, electrical, or low-voltage systems technicians in residential and light commercial settings where a clean, flush-mounted sensor is required.

The MSS-19C-W suits applications where a recessed profile is necessary to avoid interference with door or window hardware. The white finish makes it appropriate for interior installations on painted wood or composite frames. Open loop wiring configuration means the circuit is normally open and triggers on magnet separation, which is a common requirement in alarm panel and access control wiring schemes.

Key Features

• 3/4 inch recessed form factor for flush, concealed installation
• Pre-attached leads simplify field wiring connections
• White finish suits standard interior door and window frames
• Open loop circuit configuration compatible with standard alarm and access control panels
• Single-unit packaging for individual replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-installation recessed magnetic contact switch for low-voltage security and access control systems requiring a 3/4 inch open loop sensor.

Installation Notes

Installation is typically performed by licensed low-voltage or electrical technicians. De-energize the alarm or access control panel circuit before making any wiring connections. Drill the recessed bore to match the 3/4 inch body diameter and ensure the corresponding magnet is aligned within the manufacturer-specified gap tolerance. Follow NEC Article 725 guidelines for Class 2 low-voltage wiring where applicable.
