## Description

Magnetic Door Switch ,NORMALLY CLOSED When the switch is close to the magnet, the circuit is conductive(light on); when the switch is separated from the magnet, the circuit is not conductive(light off). WIDE APPLICAIONS Work with all access control and burglar alarm systems. Can be installed in wooden or aluminum alloy doors and windows. PLEASE NOTE A magnetic door contact can only provide a switching signal to the device. It cannot directly load the power supply and cannot be directly connected to the lamp. Specifications: Model: RC-33 Contact Type: NC(Normally Closed) Max. Sensor Sensitivity: 10mm¡À5mm Max. Current: 120mA Max. Voltage: 100V Working Voltage: DC0-24V Max. Contact Power: 10W Size(Approx.): 16.7 x 10.7mm / 0.66 x 0.42inch (H*D) Cable Length(Each): 30cm / 11.8inch Housing Material: ABS Wire Type: 1007#/24#300mmUL Package Content: 10 x Magnetic Door Switch

Review: Delivered on time - Haven't used them yet but I'm quite sure they're at work just fine looks good thank you.
Review: Perfect for a closed loop alarm system... - The switches designed for a "closed loop" alarm system, meaning when the window is closed the switch is shorted / ON / closed. That way if someone snips you cable the alarm will go off or you will know there is something wrong. I think that is why they call this NC switch. In reality, I might agree with some of the other reviews, the switch is open when not next to the magnet so I can see the confusion it is normally open. While they don't explain this in the description, I believe it is standard in the alarm industry to call these switches NC, other similar products posts describe NC switches this way for closed loop alarm systems.
