Let me start by declaring that I have absolutely no idea what I'm doing so please try to keep it simple if possible. Thanks in advance.
I have a project requirement that uses simultaneous input from two momentary switches (safety feature) to activate or deactivate a SPDT relay. Subsequent simultaneous inputs from the same pair of momentary switches should toggle the state of the relay.
I understand (I think) that the behavior I require is referred to as an impulse or bistable latching relay. What I'm struggling with is that I also have a requirement that the relay should reset to "off" on power loss so that when power is restored, the relay remains "off" until triggered again.
I know this is the opposite of how true latching relays work, so I'm thinking that what I probably want is a non-latching relay that's implemented such that it behaves like an impulse relay only as long as it has power. But I don't know how to do that.
Do you think this can be done with some type of relay logic or off the shelf module? or do I need to build it from scratch?
Any input is appreciated. Thank you.
