Effortless Temperature Control with a 140°F Disc Thermostat
Looking for an easy way to protect your devices or control heat in your projects? This 140°F disc thermostat is built for straightforward use and dependable performance. Designed to open at 140°F (60°C), it automatically resets once the temperature drops—providing worry-free temperature regulation wherever you need it.
Simple Installation & Everyday Use
Installation is quick and hassle-free. The thermostat includes 1/4" quick disconnect terminals for easy wiring, plus a turnable mounting bracket that lets you position it exactly where you want. No specialized tools or advanced wiring required—perfect for everyday DIYers and home repairs.
How It Works: Normally Closed, Snap-Action Switch
This model uses a snap-action bi-metal disc—when the set temperature of 140°F is reached, the normally closed thermostat opens the circuit.
