Quick-Switch Security Equipment

Thank you for Entering our store. Many clients wonder what is the difference between open and closed contacts. Pay close attention to what the contact is, open or closed, When next to a magnet. An LED style switch for say a pantry would want the contact to be open when the magnet is next to the switch, or door is closed. When you open the door, magnet separates from the switch, you would want the switch to close, sending power to the LEDs and they in turn light up the LEDs. Totally Opposite for Alarm systems. Magnet separates from the switch, window is now open, the contact closes and starts the energy flow sounding the alarm(if armed). close window and magnet is now next to the switch opening the magnetic contact stopping the sounding alarm. (not really but in this scenario) As always ask questions before you purchase.
