Essential Info

Installing a magnetic contact doesn't have to be a hassle! The US-555 contact set is comprised of a stubby, 3/8" sensor with wire leads and a long 3/8" magnet. This configuration is excellent for doors with limited space in the frame. The magnet and sensor press into 3/8" holes and Rhodium metal contacts and rare earth magnets provide reliable monitoring at a gap of up to .75 inches. This type of contact switch is for normally closed circuits; this means that the when the magnets are lined up, the switch is closed. This type of setup is ideal for monitoring doors, windows, and sliding doors. The magnetic contact is wired to most hardwired security systems to notify you when the contact is broken - when a door is opened, window is opened, etc.

I am extremely happy with Smarthome. The magnetic contacts I ordered arrived from them within 2-day after I ordered the contacts.
PAUL -- fort worth, TX   3/18/2012
Very happy with my purchase. One small problem with the original shipment, but it was easily fixed with a phone call. I would order from SmartHome again.

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.
