A rotary switch comprising a housing, a cover, three stationary contacts, a rotor, an O-ring seal, and a combination sealing and driving member. The switch is mounted on the end of a door lock cylinder assembly of a vehicle and is connected with the vehicle anti-theft system so that insertion of a key into the lock cylinder and rotation of the key in one direction arms the alarm system through the switch while rotation in the opposite direction disarms the system. The switch is entirely self-contained and weatherproof.
