This system uses a sealed bulb filled with a temperature-sensitive gas or liquid. As it heats up, the fluid expands, increasing pressure and expanding a flexible bellows or diaphragm. This movement triggers the mechanical switch. 🔌 Typical Electrical Schematic (Схема)

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. This system uses a sealed bulb filled with
. It operates by translating temperature changes into physical movement to open or close an electrical circuit or a valve. ⚙️ Operating Principle the fluid expands
