a flip-flop 18d for controlling opening/closing of the contact point of the relay during the "+" or "-" cycle of the power voltage, an AND-gate A5 for ANDing the output signal of the /Q output terminal of the flip-flop 18d and the output signal of the pulse generator 18c, an AND...
relays are for such applications. However young electronic enthusiasts often become confused while assessing the pin outs of the relay and configuring them with a drive circuit inside the intended electronic circuit.
