I am new to this website and have limited knowledge of electronics.
I'm looking to build a small unit that has a momentary switch that causes buzzer to activate and stay on until it is reset.
I have the momentary switch I want to use. I have a buzzer that I can use for now (separate question). I'm looking to do this all low voltage DC.
I think what I need is a latching relay that is triggered by the momentary switch and the latching relay than supplies power to the buzzer. Is this the correct line of thinking? Where can I learn more about which of the many relays out there I need and how to wire it?
I then need a way to reset the 'system' to turn the buzzer off.
Separately, years ago I built a little box with an electronic door bell "buzzer" rather than a "siren" type buzzer. I haven't been able to find these nicer/calmer tone buzzers - i can only find "siren" type buzzers. Thoughts on where I can find these?
Thanks so much for your help!
