What is an Electrical Switch : An electrical switch is any device used to interrupt the flow of electrons in a circuit. Switches are essentially binary devices: they are either completely on (“closed”) or completely off (“open”). There are many different types of switches, and we will explore some of these types in this chapter. Learn the Different Types of Switches : Switches can be of mechanical or electronic type, Mechanical switches  must be activated physically, by moving, pressing, releasing, or touching its contacts. Electronic switches  do not require any physical contact in order to control a circuit. These are activated by semiconductor action. Mechanical Switches : Mechanical switches can be classified into different types based on several factors such as method of actuation (manual, limit and process switches), number of contacts (single contact and multi contact switches), number of poles and throws (SPST, DPDT, SPDT, etc.), operation and construction (
