    exactly what I needed at an excellent price and fast shipment.

    I was not able to use this item. The description says "Connect drawers, jewelry boxes". However the plunger requires quite a bit of pressure to retract and open the circuit. The spring tension is not adjustable. It may work with a door or a heavy drawer but forget the jewelry box.
    THOMAS -- memphis, TN   2/17/2008
    Worked fine, I have no problems with switchs.
    PAUL -- oklahoma city, OK   12/7/2007
    Needed a couple of spare tamper switches. Original system was purchased from Radio Shack, which no longer sells many wired system components. I tried an N.O. switch from another online seller. It was backward from what I needed. The Smarthome online description made it clear that this switch is open when the plunger is depressed. That's what I needed. Thanks
