38- Collapsing Circuit – Dual Out
$26.95 – $76.95
A collapsing circuit uses the normally closed switch and the coil of the relay (RY1) and two batteries as separate circuits (e.g., the coil control circuit and the firing circuit) that are connected to the coil and switch sides of the relay, respectively. The circuit fires when the battery on the coil control circuit is disconnected.
