Reed Switches for Alarm Systems

Reed switches are used in alarm systems, they are located within the door and are known to be flush mounted. Or mounted on the door or window, surface mounted .One part of the contact is a switch installed in the window or door jam; the other contains a magnet and is placed in the window or door itself. 

Any noticeable shift in contact with the switch breaks the magnetic field and triggers an alarm.

Check out our huge selection range of reed switches from leading brands Bosch, Risco, Sentrol, and Tane.

Flushmounted Reed Switches
Reed Switches as they are often called can be either recessed or flush mounted.
A hole is drilled inside the door jam and the reed switch is inserted. 
Flush mounted reed switches are often more inexpensive, but do require extra labour for installation.

Surface Mounted Reed Switches

Surface mounted reed switches are mounted to the surface of windows or doors, these reed switches are often available in multiple colours to blend in with home or office décor/ window frame to be discreet.

Surface mounted reeds can also be used for roller doors.
