ELECTRIC CIRCUIT IN DEVICE HAVING INTERMITTENT OPERATING ELEMENT, PARTICULARLY AUTOMOBILE-TROUBLE ALARM

摘要

PURPOSE: To realize an operation electric circuit for a pilot lamp in the fault alarm device of automobile in a desired drive form at a small circuit cost. CONSTITUTION: A pilot lamp and flasher unit interconnecting wiring 7 is led to a drive output terminal 8 at least with respect to one intermittent operating element (flashing lamp) 12, an active switch 4 is a multi-planer switch having at least two permanent switching positions, its 1st switching plane B is in loop connection to a blinker active control wire 6 and its 2nd switching plane A is in loop connection to the pilot lamp and flashes unit interconnecting wiring 7 respectively, the intermittent operation of the element 12 is active at a switching position via the 1st switching plane A and the pilot lamp and flasher unit interconnecting wiring 7 is electrically connected via the 2nd switching plane A synchronously therewith.
