The switch is an electrical device that is used to break or make an electrical circuit manually or automatically. The working principle of switch depends on ON/ OFF mechanism. Various electrical or electronic circuits use switches to control or trigger the owl circuit. The types of switches depend on the connections of the circuit they make. 5. Your electronics are now ready to be shredded to produce raw materials that are later used for manufacturing new products. 6. Don’t forget the money! Your waste is precious, so you can actually SELL it to these recycling I want to end with some interesting statistics by the U.S. Environmental Protection Agency (EPA).

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, […] Here the switch conducts normally, but interrupts the circuit when you press on it. This is more specialized, and may be used in conjunction with a wiring trick. For example, connecting a normally-on switch in parallel with a light bulb will light the bulb when the button's pushed; otherwise, current will flow through the switch, leaving the bulb off.
