Description
The bimetal thermostat shows that dissimilar metals expand (or contract) at different rates, and thus may be used to close or open an electrical circuit at specific temperatures. Circuit is completed when temperature either rises above a certain point or falls below another point. Temperatures are set by two screws. The inscription reads "Chicago Apparatus Co. / Chicago USA."
