发明名称 Electronic time switch
摘要 An electronic time switch for the time-limited actuation of appliances which are supplied with alternating current, whose load component is actuated by an electronic control element, and which includes terminals which supply the load component as well as the control element. A first storage element is charged during the inoperative condition through a rectifier, wherein the first storage element charges a second storage element upon initiation of load operation through the intermediary of a pushbutton with switching functions, through a recharging branch having a current limiting resistor. The recharging branch consists of a parallel circuit including an ohmic resistor and a threshold rectifier.
