An electrical switch is a device used for changing the flow of a circuit. Electrical switches may be categorized by various factors, such as the type of actuator they use. The actuator is the moving part that applies force to the contacts and may be a toggle, pushbutton, rocker, or dial.
Two of the most common types of electrical switches are single-pole and double-pole switches. The simplest type of electrical switch is a single-pole (SP) switch. SP switches have two points, called contacts, that connect to make a circuit and separate to break the circuit. Double-pole (DP) switches, in comparison, have two “on” positions and one “off” position. For example, the fan button on kitchen range hoods has a high-off-low configuration where the two “on” positions provide different voltages.
Another type of electrical switch is the momentary-contact switch, which is either normally closed (N.C.) or is normally open (N.O.). One use for this type of switch is as computer power switches. A computer uses a normally open switch which, when activated, closes the circuit, sending a message to the motherboard to turn power on/off.
