A rotary switch assembly for use with a fuel burner valve having a user rotatable shaft. The switch has an annular sleeve which upon being received over the valve shaft is engaged to be rotated by the valve shaft. The rotor has a conductive contact ring frictionally engaging the rotor with inward projections on the ring frictionally engaging torque transmitting grooves formed on the rotor. The rotor is journalled on the switch base which has stationary contacts provided on opposite sides of the rotor. User rotation of the valve shaft causes the rotor to rotate and the wiper contacts complete a circuit between the stationary contacts.
