Product Research


Overview: The InstallBay magnetic reed switch can be used with just about any vehicle alarm system for protecting doors, hatches, tailgates, and more. The "reed" side of the switch is normally closed and when in contact with the "magnet" side of the switch, will open up the circuit, breaking the connection on the two wires.
