What is another word for bimetallic strip?
Pronunciation: [ba͡ɪmɪtˈalɪk stɹˈɪp] (IPA) 
A bimetallic strip is a device made from two different metals that are joined together. The strip can be used as a thermometer, a thermostat, or as a safety device to control the temperature of a room or an appliance. Synonyms for bimetallic strip include thermal switch, metal thermostat, temperature switch, thermal bimetal strip, bi-metallic element, and dual-metal strip. These pieces of metal can also be referred to as a thermomechanical strip, or simply a bimetal strip. Regardless of the name, they all function in a similar way; the two metals expand and contract at different rates, which results in a bending or curling of the strip that is used to control a range of applications.
