Abstract
A time switch has a resetting, movable switching member on which there is provided a suction cup which can be pressed against a counterpart body. The cross-section of an air inlet opening (9) into the reduced-pressure space between the counterpart body and the suction cup when pressed against the counterpart body determines the switching time and is preferably adjustable. A venting opening with which a removable closure element is associated additionally opens into the reduced-pressure space.
Claims4
A time switch comprising:
- a switching member on which a suction cup is arranged,
- a counterpart body against which the suction cup is pressed forming a reduced-pressure space, with air contained in the suction cup being displaced,
- an air inlet opening into the reduced-pressure space, wherein said opening has a cross-section to establish the release time of the suction cup from the counterpart body,
- a resetting device whose resetting force is less than the suction force of the suction cup when pressed against the counterpart body, and
- a venting opening associated with the reduced-pressure space comprising a sealing closure element which is urged in the closed position.
