MSS-303C MAGNASPHERE Switch Recessed Recess Security Contact

Review MAGNASPHERE Switch Recessed Security Contact

Introducing the Magnasphere MSS-303C Switch Recessed Security Contact, a revolutionary addition to your home security system. This contact is meticulously designed to provide maximum security and reliability for your doors and windows.

The MSS-303C is a recessed switch contact, meaning it is designed to be installed flush with the wall, providing a sleek and unobtrusive appearance. It is suitable for use with single-pole, single-throw (SPST) switches, making it a versatile and adaptable choice for various security applications.

This contact features a robust and durable construction, with a zinc alloy housing and a brass arm contact for superior conductivity and longevity. It is designed to withstand the rigors of everyday use, ensuring reliable operation for years to come.

One of the standout features of the MSS-303C is its patented Magnetic Sensing Technology. This technology utilizes a powerful magnet to detect the presence or absence of a securely closed door or window. When the contact is closed, the magnet is aligned, allowing the switch to be turned on. If the contact is opened, the magnet is disaligned, and the switch is turned off. This creates a reliable and secure connection that cannot be easily tampered with or bypassed.

The MSS-303C is also designed with ease of installation in mind. It can be installed in just a few simple steps, without the need for any additional tools or wiring. The contact comes with a pre-installed adhesive strip, allowing you to attach it directly to the door or window frame. Once installed, the contact can be connected to your home security system using standard wiring.

For added convenience, the MSS-303C also features a built-in LED indicator light. This light illuminates when the contact is closed, providing a visual confirmation that the door or window is securely closed and the contact is functioning properly.

In summary, the Magnasphere MSS-303C Switch Recessed Security Contact is a top-of-the-line security solution for your doors and windows. With its robust construction, reliable magnetic sensing technology, and easy installation process, it is an essential addition to any home security system.
