The latching relay shown latched in Fig. 1 is selected and latched or not latched by a signal at one input. The electrical path to the magnet latch coil for the latching arm is separated from the input by a capacitor. A short pulse passes the capacitor and drives the latch coil so as to hold back the latch, while a long pulse is blocked by the capacitor and the latch operates.
