While specific diagrams vary by application, the basic electrical schematic of a mechanical thermostat is exceptionally simple. It operates as a temperature-controlled, single-pole switch. Standard 2-Wire Heating Circuit No software to crash or digital boards to fail

Contacts can arc and degrade over years of use. It operates as a temperature-controlled, single-pole switch

Resistant to voltage spikes and extreme ambient temperatures.

In a basic heating system (like an electric baseboard or a simple boiler control), the thermostat is wired in series with the power supply and the load.

Two different metals with distinct rates of thermal expansion are bonded together. As the temperature changes, one metal expands more than the other, causing the strip to bend. This bending physically pushes a contact to break or complete the circuit.
