The position of the contacts when the coil is de-energized is used to define their state as being either Normally Open (N.O.) or Normally Close(N.C.)

This Switch contacts can be open or closed. Closed contacts can conduct current through the switch, while open contacts can not conduct current. A spring-loaded switch uses spring force to hold the contacts in one position or the other. The switch can have multiple sets of contacts, so some contacts can be NC, while others are NO on the same switch.

Alarm Contact switches are magnetic switches used to protect doors and windows for the most part. Doors are the most common place of entry and should be protected by your alarm system. The Home Security Store always recommends contacting every perimeter door in your home or business.
