A flashlight has a cylindrical housing holding a light source. A switch on the housing has an actuating element rotatable about a longitudinal axis of the housing. The housing has a surface directed toward the actuating element and formed with a recess open toward the actuating element. A permanent magnet on the actuating element and directly juxtaposed with the housing surface is engageable in the recess in a predetermined angular position of the actuating element. A spring braced between the permanent magnet and the actuating element biases the permanent magnet toward the housing surface. A contact element inside the housing is operable magnetically by the permanent magnet.
