In the 120V circuits of homes and offices, the grounded conductor is the same as the neutral. Typically, when wiring a switch for a 120V load (e.g., a light) only one wire comes to the switch and only ...

Switch is an electronic device which stops the circuit and transmits the current to conducts. It is a binary devices which means that it has two states; the on state or “closed”condition or off state ...

Electronics keep shrinking, but silicon is starting to run into physical limits. To go smaller, researchers are turning to ...

Some engineers, as well as many non-engineers, might be unaware that electrical switches benefit from being lubricated. In fact, for many electrical switches, lubrication is required if they are going ...

Note: This article references the 2017 NEC because the Philadelphia area — the jurisdiction where this author teaches and works— is still operating under that version of the Code. Electrical switches ...
