A vibration switch includes an optoelectronic sensor member with light emitting and receiving units disposed in an insulating housing. A light-transmission rollable member is received in the housing, is disposed on a light beam route confined by the emitting and receiving units, and is movable between a rest position, where the rollable member interferes with a light beam emitted from the emitting unit such that the resultant light beam received by the receiving unit has a first light intensity, and a liable position, where, due to a jerking force acting on the housing, the resultant light beam has a second light intensity which differs from the first light intensity by a predetermined quantity such that an actuator can be actuated to put electric contact terminals in one of switch-on and switch-off states.
