Magnasphere Corp MSS-312C-BLACK Magnetic Contact Switch

Product Description

The MAGNASPHERE CORP MSS-312C-BLACK is a magnetic contact switch assembly designed for special application security and access control circuits. It includes one receiver unit paired with three switch contacts configured as two normally closed and one normally open, providing flexible circuit monitoring in a single package. Electricians and low-voltage security technicians install this type of component in door, window, or access panel monitoring systems where multiple circuit states must be supervised simultaneously. The black finish suits installations where aesthetics and surface matching are a consideration.

This switch assembly is suited for special application contact installations where standard single-contact sensors do not meet circuit requirements. The combination of two normally closed and one normally open contacts in one receiver makes it appropriate for commercial and residential security panels, access control systems, and industrial monitoring applications where multi-state detection is required. It is sold as an individual unit.

Key Features

• One receiver with three switch contacts in a single assembly
• Two normally closed contacts and one normally open contact for versatile circuit wiring
• Black finish for discreet surface-mount installation
• Classified under special application contacts for advanced monitoring requirements
• Sold individually as a complete assembly

Compatibility

Designed as an OEM-style replacement or direct installation component for special application magnetic contact switch circuits requiring a multi-output receiver configuration.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage technician in accordance with applicable NEC requirements for signaling and access control circuits. De-energize the circuit and verify zero voltage before making any wiring connections. Follow the manufacturer product manual for correct receiver and switch magnet alignment, as improper positioning can cause false open or false closed circuit readings. Do not exceed the rated electrical parameters for the switch contacts.
