Hello. I am a small time tinkerer and I am stuck. I have a 1.5v dc digital timer and I want to replace the stock speaker with piezo siren that operates between 6-14v DC. Here is the link: Siren. From what I understand I will need a solid-state relay to connect the speaker output to the piezo siren and battery. I have searched 5 different stores and and searched the web, but I could not find a relay that would work at that low voltage. I hope that someone may know of a relay that would work, or know of a different way to do this project. I appreciate any help.
