A two way switch has 3 terminals. A three-way wall switch is a common type of light switch that makes it possible to control a ceiling light or other electrical fixture from two different locations in a room. There are single pole switches controlling things from a single location, three-way switches controlling lights or outlets from two locations, and for larger homes or complicated situations, a four-way switch may be used to control lighting or outlets from three or more locations. The light is ON when the COM terminal of both the switches is connected with L1 or L2 terminals. Add up the wattage of the bulbs in all the fixtures the switch controls to make sure it falls within the switch rating listed on the package or instructions. The other is not. The switch is on when the COM terminal and L, There are three types of circuits they are open circuit, close circuit, and short circuit. If we flip switch1 we complete the circuit electricity flow through switch1 into switch2 then back to switch1 and up into the lamp. However, the usage of two switches isn’t decreasing too. switch wiring is similar to the EX-OR gate in terms of digital. The terminologies related to switches are different between the US and the UK. Touch the probes to the 3 wires removed from the switch until you get a reading on the tester indicating continuity. Then connect a another wire from terminal L1 in switch1 to terminal L1 of switch2. The one gang two-way switch is used when two switches control the single bulb. The L2 terminals of both the switches are connected to one terminal of the light bulb while the other terminal of the light bulb is connected to neutral of the AC power supply. Finally run the blue wire from terminal L2 of switch1 from to light fitting. Two Way Switch or Three Way Switch: “Three-way” is the North American (USA) term for this type of switch used in the following tutorial.Most English-speaking countries (UK/EU) call them “two-way”. The live is in L1 and the neautrals in L2. Here is a question for you, how does a Double Pole Double Throw switch works? Then, we go to the end of the hall, and turn off the light. Set the electrical tester to the continuity or ohms setting. A four-way switch configuration is composed of two three way switches, one on each "end" of the switching circuit and a special four-way switch in-between the two three-way switches. Now go the other switch location. Live is connected to common of switch 1, while t he L1 of both switches connected together and t he L2 terminals of both switches connected together..
