A thermostat is temperature sensitive switch that controls automatically the operation of heating or cooling devices by responding to changes in temperature by sensing the ambient temperature, and changes of ambient temperature are sensed by a temperature sensor (a bimetal disk). The temperature sensor is displaced in its curvature state when its temperature exceeds a first set temperature, and later returns to the initial curvature state when the temperature of the heat sensing element drops below a second set temperature, and the on/off state of the switch contact is shifted by making use of this property. Thermostats are used to control a variety of heating and cooling systems. A variety of thermostats have been developed for use with the various types of heating systems. Mechanical thermostats employ an expanding, temperature-sensitive mechanical member connected to a switch to turn an actuating device on or off. Pre-selection of temperatures is often accomplished by plugging or unplugging a series of small pins into receptacles on a clock driven wheel. Programmable thermostats allow a user to save energy by automatically controlling ambient temperature to different user pre-selected values during various times of a day.
