Bimetallic Thermostat Switch Model

This thermostat switch model uses a vertically mounted bimetallic strip to demonstrate how a thermostat opens and closes an electrical circuit in response to temperature changes. The apparatus consists of binding posts for connection to low-current circuits and adjustable contacts. The demonstration effectively illustrates the principle of differential thermal expansion in bimetallic strips, a concept central to thermodynamics and the design of temperature-regulating devices in everyday applications.
