Mechanical Cabinet Thermostat – Normally Open / Normally Closed Temperature Controller

Need a simple, reliable way to control temperature in a small enclosure or cabinet?

This mechanical thermostat gets the job done.

It’s a basic, no-frills unit that can be wired as normally open or normally closed, depending on your setup—whether you’re controlling a fan, a heater, or just monitoring heat levels.

No digital screens, no batteries, just a solid mechanical switch that clicks when it hits the set temp.

Perfect for reptile enclosures, fermentation chambers, or electronics cooling.
