STOP SWITCH

A stop is a part designed to restrict the movement of a rotary mechanism, linear (sliding) mechanism or its components. It protects a mechanism from loss of adjustment or damage due to extreme movement. A stop or stopper may also be designed to calibrate and halt the flow of solids, liquids or gases.

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.
