2. Multiway switching - Wikipedia

   en.wikipedia.org/wiki/Multiway_switching

   These switches appear externally similar to single pole, single throw (SPST) switches, but have extra connections which allow a circuit to be controlled from multiple locations. Toggling the switch disconnects one "traveler" terminal and connects the other. Electrically, a typical "3-way" switch is a single pole, double throw (SPDT) switch. By ...

   The Canadian Electrical Code, while developed independently from the NFPA code, is similar in scope and intent to the US NEC, with only minor variations in technical requirement details; harmonization of the CEC and NEC codes is intended to facilitate free trade between the two countries.

   3 Australian light switches and a "neon" indicator—in a 4-gang wall-plate. The lower switch is in the "on" or "down" position. Two Australian rocker switches (disassembled), together with a cutaway view, and a view of the switch connections An Australian architrave-mounted 2-gang switch plate and switches.

   When switches, socket outlets or light fixtures are replaced, the mere act of tightening connections may cause hardened insulation to flake off the conductors. Rubber insulation further inside the cable often is in better condition than the insulation exposed at connections, due to reduced exposure to oxygen.

6. Dimmer - Wikipedia

   en.wikipedia.org/wiki/Dimmer

   European dimmers must comply with relevant EMC legislation requirements; this involves suppressing the emissions described above to limits described in EN55104. In the electrical schematic shown, a typical light dimmer based on a silicon-controlled rectifier (SCR) dims the light through phase-angle control. This unit is wired in series with the ...

   Arrange the carrots and potatoes in a single layer in a 6-quart slow cooker. Scatter the garlic, thyme, and shallots over the top. Season with the remaining 2 teaspoons salt and 1/2 teaspoon ...

8. Double switching - Wikipedia

   en.wikipedia.org/wiki/Double_switching

   Double switching is a crucial safety engineering practice in railway signalling, wherein it is used to ensure that a single false feed of current to a relay is unlikely to cause a wrong-side failure. It is an example of using redundancy to increase safety and reduce the likelihood of failure, analogous to double insulation. Double switching ...
