Circuit Diagram The most familiar form of switch is a manually operated electromechanical device with one or more sets of electrical contacts , which are connected to external circuits. Each set of contacts can be in one of two states: either "closed" meaning the contacts are touching and electricity can flow between them, or "open", meaning the contacts are separated and the switch is nonconducting. The mechanism actuating the transition between these two states (open or closed) is usually (there are other types of actions) either an " alternate action " (flip the switch for continuous "on" or "off") or " momentary " (push for "on" and release for "off") type. A switch may be directly manipulated by a human as a control signal to a system, such as a computer keyboard button, or to control power flow in a circuit, such as a light switch . Automatica
