Bimetal Strip with Electric Contact - code: 4200.80

Simple demonstrator for thermal expansion. A simple device that shows how we can use two different metals joined together to produce a thermostat. The apparatus consists of a bimetal strip that expands differently on both sides due to two different materials. Once heated, it will bend to one side as one of the metals will expand faster than the other.
