    Installation
    Simply drill a 3/8" hole in the edge of a door or window jamb and press fit. The wires are can be 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" of 22AWG wires and handles up to 1 Amps at 10 volts DC. It can reliably operate in temperatures between -15°F and 160°F. Rated for 50 million openings and closings, this thing will never wear out!

    Contacts are closed when magnet and sensor are together.

    LARRY -- concord, NC   10/31/2011
    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.
    RANDY -- humble, TX   6/27/2011
    Fast shipping
    DUSTIN -- senoia, GA   6/18/2011
    Worked great. Had to replace a few contacts. I used the long ones on the doors.
    GEORGE -- newark, DE   3/24/2011
    Dear Sirs, The problem is the sensor opens over night when the temperature goes down causing the door indicator led to come on. It closes again when it warms up outside. I have an extra uninstalled magnet I used to verify the contacts will open and close. I assume it is the magnet in the door. Thanks, George
    WALTER -- wauseon, OH   11/9/2010
    easy to install, works great.
    ROBERT C. -- jacksonville, FL   9/9/2010
    "Normally closed" in this case means the switch is closed when the magnet is near by. I needed a switch that was closed when the magnet wasn't near it. But otherwise a fine product.
    DENNIS -- davie, FL   8/23/2010
    Great product, works just as advertised.
    ROBERT -- massillon, OH   7/31/2010

    WESLEYV -- jefferson hills, PA   11/30/2008
    Purchased to install in new doors I had installed. Easy to install.
    JOSEPH -- severn, MD   10/20/2008
    Appears to be a well made product although specs do not indicate if contacts are sealed reed type. If not, long term reliability could be affected.
    ARTHUR -- thousand oaks, CA   2/1/2008
    The magnet was not strong enough to activate the reed relay switch.
    DAVID -- falls church, VA   1/10/2008
    Perfect fit -- exactly what I needed.
    TOMAS -- port charlotte, FL   12/22/2007
