THERMOMETER / LIGHT SWITCH COM

In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. Switches of all types are used in the operation of restaurant equipment. The most common type of switch is an electro-mechanical device consisting of one or more sets of movable electrical contacts connected to external circuits. When a pair of contacts is touching, current can pass between them, while when the contacts are separated no current can flow.

A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. Thermometers are primarily either electrical or mechanical, having a measuring or sensing component and a means of display or output. Thermometers of different types are used throughout the foodservice industry for the measurement and regulation of temperature in equipment used for refrigeration, cooking, frying, holding and merchandising, beverage service, and more.
