Abstract
An electric circuit arrangement to replace the combined pushing and locking electric switch of the type used in DC fed automobile blinker systems, characterized by a signal detection unit controlled by a push switch and comprising a timer member, an integrating member and a bi-stable storage member whose output controls a blinker relay or subsequent electric component. Actuation of the push switch generates a pulse which directly controls a flip-flop and a timer member as a function of the length of time of actuation of the push switch, the length of such time in relation to the setting of the timer acting to set or re-set the flip-flop. Two push switches are provided which control the timer and two bi-stable flip-flops whose outputs are cross-coupled.
