  • What's Included
  • Eliminate the telltale signs that you have an alarm system installed. Unlike conventional magnetic contact switches, these switches are completely hidden. The Long Round Magnetic Contact Switch is 1.3 inches long and is ideal for doors, and short round magnetic contacts ideal for windows are sold separately. Each contact has an operational gap of one inch.

    Simply drill a 3/8 inch hole in the edge of a door or window jamb and press fit. The wires are passed through the jamb and framing and run over to the alarm system controller. Both the switch and wire are completely invisible when the door or window is closed. Mount the magnet in the door or window so that the two are in contact with each other when the door or window is closed.

    Other Features
    The contact switch is waterproof and enclosed in an epoxy compound that is moisture and corrosion resistant. The high-impact plastic case withstands hammering in of the switch and magnet. Comes with 15 inches of 22AWG wires and handles up to 1 Amps at 10 volts DC. It can reliably operate in temperatures between -15&degF and 160&degF. Rated for 50 million openings and closings, this thing will never wear out!

    Contacts are closed when magnet and sensor are together.

    Wasn't clear to me what "normally Closed" means - I think this should be explained on the item description. Probably works, tho. Normally closed means that when the magnet is next to the contact, it is closed. Depending on your installation, that may or may not mean "normal".

    Received item as advertised and within forecasted timeframe.

    Good price but expensive shipping on small parts.

    Easy installation.

    A good source for alarm system parts.

    Item has proved to be reliable over 23 years in service. Ordered these as replacements/additions for remodel. Price and shipping were great from Smarthome. Well pleased with service.
