The MSS200-7 BMS High Security Magnetic Contact is a 3/4″ recessed contact that works well in wood and steel doors where a small concealed contact is preferred. The UL Listed magnetic contact has one CC door switch and one OC magnetic tamper switch when magnet is present. There are three color coded wires and an adjustable rare earth magnet. This is the most popular Flair high security contact and the patented case locks into several gauges of steel doors as well as wood doors. Provide your customers more than just a door switch, give them time tested inexpensive Flair high security contacts with built in magnetic tamper.
