Two sets of alarm surface door contacts, enough for two doors but can be fitted to either doors or windows. Each half of the contacts measures 67mm x 12mm x 13mm approx and they have an operating gap of 20mm. As you can see in the pictures the contacts come with fitting screws. The part of the contact that has five terminals on the back, holds the magnetic reed switch. The other part of the contact holds a magnet, either an alnico V or ferrite type.
