Relay zener

👀 A Demonstration of the behavior of different types of Relays. Here we have; 🙈 A Noramally Open Relay 🙉 A Noramally Closed Relay 🙊 A Combination Relay 🐒 Adjusting the Supply voltage will act to then adjust the current passing through each of the relays coils. 🐒 Once the current has reached a sufficient level ~ 50m is presently set ~ The relays will actuate to their On positions. 🐒 Once the current drops below a given level ~ 25m is presently set ~ The relays will release, and revert to thier Off positions.
