【Material】The Magnetic Switch is made of flame-retardant ABS shell material, resistant to high temperature and not easy to deform.
【Normally open (NO)】Normally Open type with 2 wires, When the switch is separated from the magnet, the circuit is conductive(light on); When the switch is close to the magnet, the circuit is not conductive(light off).
【Application】This magnetic contact switch is usually used for metal door/windows include rolling Door. The door contact can be used with an access control or anti-theft alarm system.
