摘要:
A hazard indicator including a power-saving control circuit having a transistor with a collector connected via a resistor to the output of the signal processing circuit. In operation, the transistor delivers the clocked control signal for the semiconductor switch as a function of the current-proportional voltage applied to the base of the transistor.
