Electronic timer

摘要

Electronic timer for time-limited switching-on of loads which are fed with alternating voltage, for example lamps, the load section of which is switched by an electronic control section and which exhibits connections for load section and control section. It is provided that the connections of the load section, at the same time, feed the control section in that a store is charged up via a rectifier in the no-load condition, which store charges up a second store feeding the control section when load operation is initiated by means of a key with switch-over function. <IMAGE>
