QMseller MC-33C Normally Closed Recessed Window Door Contact Sensor Alarm Magnetic Reed Switch 2 Sets
Work as an anti-theft alarm, ideal for metal door and window.
NC means Normally Closed:When the magnet together, the circuit is conductive( light on ).
when the magnet separate, the circuit is not conductive ( light off ).
These are the door contact sensors that are in use with any and all commercial or residential card access systems as well as all security burglar alarm system.
▲ PREMIUM MATERIAL AND DURABILITY - Industrial grade GCr15 bearing steel construction ensures durability and tool longevity to withstand professional uses.
▲ EXCELLENT CUTTING PERFORMANCE - All cutting teeth are precisely CNC machined and accurately heat treated to Rockwell hardness 60 HRC for best threading performance.
▲ VERSATILITY AND TAPERED TEETH DESIGN - Perfect to create new threads or repair damaged threads on most metals like carbon steel, cast iron, aluminum, brass, copper and stainless steel.
Taps (for internal threads) and Dies (for external threads) feature with tapered teeth that start threading more easily.
