Product Description
This is a Heat Switch (Thermostat) Demonstration Apparatus by Ankidyne, designed as an educational physics lab teaching aid to demonstrate the working principle of a thermostat/bimetallic strip heat switch. The apparatus visually explains how heat causes expansion of a bimetallic strip, which bends and either makes or breaks an electrical circuit the core principle used in thermostats, fire alarms, electric irons, and refrigerators.
