Die Anfrage
“24 V DC motor start/stop control: a normally closed overload contact and a stop button in series, a start button that energises relay K1, an auxiliary K1 contact that latches it in, a main K1 contact that runs the motor, and a diode across the coil.”

Was diese Zeichnung zeigt
Die dahinterstehenden Entscheidungen verstehen.
01
Use a holding contact (K1_AUX) in parallel with the start button to latch the relay.
02
Place a normally closed overload contact (S_OL_NC) in series with the control circuit to stop on overload.
03
Include a flyback diode (D1) across the relay coil to suppress voltage spikes.
