The basic electrical circuit includes a power switch, and a load connected in series with the power switch, connected across the output terminals of a power source. Typically, the power switch is a mechanical device which makes or breaks an electrical contact. The electrical contact is made or broken by a mechanical force provided either manually or through a magnetic field. Switches are commonly employed as input devices to indicate the presence or absence of a particular condition in a system or process that is being monitored and/or controlled. As the use of electrical equipment in the home and commercial establishments increases, there is a need to increase the number of electrical switches used for controlling or supplying electrical power to such equipment. Switches ordinarily are used to control the flow of electrical current to a variety of devices which operate by electricity. Switches can be designed various forms to respond to any type of applications. It is therefore not surprising that an almost incomprehensible variety of rotary switches, rocker switches, toggle switches, membrane switches, slide switches, key switches and pushbutton switches are offered, in every imaginable shape, color and size. Toggle switches are provided with levers that must be pulled or pushed to release a lock prior to pivoting the lever for switch operation. Rocker switches have a plurality of terminals and means operated by a rocker for making and breaking electrical connections between pairs of those terminals. A reed switch consists of a pair of ferrous metal contacts in a hermetically sealed glass envelope. Membrane switches are touch activated to make or break the electrical connection of a particular switch element. In general, manually operated switches include an actuator that is manually actuatable to cause making/breaking action of switch contacts to energize/de-energize one or more electrical circuits associated with the contacts.
