Drive circuit for a latching relay |
摘要 |
A drive circuit for a latching relay includes a flip-flop, a timer and a semiconductive switching circuit for the relay. First and second input signals are applied to the flip-flop and first and second control signals at the output of the flip-flop are applied alternately to the timer as a time limit output for controlling the energization of the switching circuit in concert with a high-speed changeover signal.
