Merten Card Switch Insert 1-Pole with Separate Indicator Light MEG3760-0000

Hotel guests expect seamless room energy management, and the Merten Card Switch Insert MEG3760-0000 delivers exactly that. Installed flush-mounted in a standard System M frame, this 1-pole card switch insert activates room power only when a key card is inserted. A separate indicator light provides clear visual status, while the momentary switching principle controls an external relay for reliable latching. With screw terminals and a rated current of 10 A at 250 V AC, it handles typical hotel room loads with ease. The polycarbonate housing in polar white (RAL 9010) blends into any interior, and the IP20 rating suits indoor use. Operating from -5 to +40 °C, it is built for daily hotel operations.
