Improvements relating to trigger circuit
Реферат: 1286515 Pulse generating circuits ROBERT BOSCH GmbH 17 Oct 1969 [18 Oct 1968] 51059/69 Heading H3T [Also in Division G4] An astable triggering circuit comprises two semi-conductor elements 11, 12 and a switching relay 26 having a first switching path 28-32 connectible into a load circuit, e.g. of flasher lamps 34, and a second switching path 28-31 arranged in parallel with the switching path of element 11 which is conductive when the relay is inoperative. A vehicle direction indicator switch 33 initiates the sequence of operations of the multivibrator. The second switching path including resistor 30 prevents incorrect operation due to switching transients on the supply lines.
