Relays - Button Push To Control Two Relays Using RB1224

If you have a need to control two inputs with the push of a single button, the drawing below illustrates the use of an Altronix RB1224 relay. The design below shows a momentary button but could also be the normally open output of another relay or a latching button. When the button is pushed, the two onboard relays change state. The C and NO terminals will be closed (conductive). The C and NC terminals will be open. The relays will remain in that changed state as long as the button is held closed.
