Looking for a mechanical line voltage thermostat

Hello friends.

I'm looking for something not digital, not programmable, and not smart. Like me.

Thanks in advance.

    Honeywell makes them used on electric baseboard. Check Supply House.com. I have used the Honeywell T410 but they are sometimes not that accurate. There are many others. If you get a digital one they are more accurate.

    Hi Ed

    Thanks for getting back to me so quickly!

    All I need is something that sends 120V or zero volts depending on whether the circuit is closed or open, like a light switch.

    Super helpful and I really appreciate it.

    Honeywell used to offer the T451A. I don't know if they're still around. Not very accurate with the bi-metal helix.

    +1 for the Honeywells, although I would expect the others to work fine too. Pay attention to the current. Honeywell has a few flavors, switching current being part of the mix. The heat/cool stat is low current on the cooling side—it expects to be switching a contactor—but the heating leg will switch it's load directly.

    Two stage will allow you to be clever if you want, but if not pay attention to which set of contacts you use, there's an offset between them.
