I have a doorbell that has a relay to open the door. The issue I'm having is that my doorbell is outside the house and thus people would be able to come up to the doorbell, open it, and connect it themselves. I don't want that to be possible.
Thankfully, my doorbell also has a tamper switch. This is a contact that is closed when the doorbell is normal, but when its housing is opened, the contact becomes open. That way I can securely connect my door.
Now, I don't just want to connect these in series, because the tamper switch is also outside the house and a clever burglar could see the cables and trigger both at once.
I tried to check out latching relays, and I bought the CK21 switch (like this). Turns out, I can't figure this thing out. I want to connect it so that this button is inside the house and unlatches if someone triggers the tamper switch. Then, when the tamper switch is reconnected, I would need to re-set this button to reactivate the front door.
Is there a way to do this with this button? Or did I buy the wrong thing? I should also mention that all this runs on 24 VDC.
