A 2-way switching connection means you can control an electrical equipment like bulb by two switches placed at different places, generally used in the staircase two way switch can be operated from any of the switch independently, means whatever be the position of other switch(on/off), you can control the light with other switch. Light switch circuit. The first light switch employing "quick-break technology" was invented by john henry holmes in 1884 in the shieldfield district of newcastle upon tyne the "quick-break" switch overcame the problem of a switch's contacts developing electric arcing whenever the circuit was opened or closed arcing would cause pitting on one contact and the build.
light switch circuit
Wire a light switch in one way lighting circuits a simple lighting circuit is where the light switch is installed between the supply and the light fitting a common place to find in-line switches can be in an attic, in a garage or a shed. 1) light activated day night switch using transistors. the first diagram shows how the circuit can be configured using transistors, the second and the third circuits demonstare the principle by using cmos ics while the last circuit explaines the same concept being implemented using the ubiquitous ic 555.. Most electronic circuits contain an on/off switch. in addition to the on/off switch, many circuits contain switches that control how the circuit works or activate different features of the circuit. one way to classify switches is by the connections they make. if you were under the impression that switches simply turn circuits on and off, […].
