Alarm Contact switches are magnetic switches used to protect doors and windows for the most part. Doors are the most common place of entry and should be protected by your alarm system. The HomeSecurityStore.com always recommends contacting every perimeter door in your home or business.

The magnetic contact switch is the first line of defense in a security system. HomeSecurityStore.com provides a wide selection of security alarm contact switches including: Surface mount alarm contacts, Recessed alarm contacts, Commercial alarm contacts, Alarm magnets and Pill alarm contacts and Overhead door contact.

Hardwire contacts are the most common way to protect doors and windows. They are inexpensive, reliable, and usually last for many years.

They come as a set consisting of a sensor and magnet. The sensor contains a reed switch in a sealed glass tube. Reed switches are very sensitive, and are designed to be activated when placed near the magnet.
