A switch is an electrical device that controls the flow of current in a circuit. Every electronic and electrical application uses at least one switch to turn the device on and off. Switches are also categorized into two types which are electrical switches and mechanical switches.
One-way (unipolar), two-way (bipolar) are two types of switchgear. The two-way switch is used to turn on/off the light, fan from two different locations.
This article discusses the bidirectional wiring switch's function, operation, and circuit diagram.
What is a bidirectional switch?
A two-way switch (bipolar) is used to turn on and off the light from two different locations and the switch is used mostly in the case of stairs, in rooms with two entrances. This type of switch is generally used in some home wiring systems and industrial applications.
Two-way switch wire
COM, L1, and I are the three terminals of the two-way switch. The terminals L1 of both transformers are connected in phase, and the terminals L2 of each of the transformers connected to one end of the lamp terminal and the other end of the lamp terminal are connected to the neutral AC source.
The wiring diagram of a three-wire two-way switch is shown in the figure below.
The lamp lights up when the COM terminal of both switches is connected to the L.1 or L2 terminals. The light is off when the switch's first COM pin is connected to the L.1 terminal and the second COM switch is connected to the L.2 terminal. Similarly, the light turns off when the first COM terminal is connected to the L2 terminal and the second COM switch is connected to the L.1 terminal.
Omni-directional switching
There are three types of circuits which are open circuit, closed circuit and short circuit. When the switch is in the off position, the circuit is said to be an open circuit. The terminology for keys varies between the United States and the United Kingdom. In the UK they refer to a two-way switch and transit. In the US they refer to three-way switch and four-way switch. US terminology used in this interpretation.
Let's start with the basic idea of a light switch in an electrical circuit. The basic circuits for turning the light on and off are shown in the figure below.
Basic circuits to turn the light on and off
Suppose you have two different entrances to a room. Now you need different types of switches called triples, maybe because they have three contacts.
Between the two switches, the two lines are called travelers. So now you can turn the light on and off by the first switch and the same for the second switch or you can turn the light on with the first switch and off with the second switch.
A quad switch is typically used to control the light from more than two different locations, and is simply a crossover switch or a two-state cross switch.
This switch is installed between the other two switches and toggles the active switch travelling. This means that any switch has the light on or off, with this concept you can add an endless four-way switch to the circuit. The multidirectional switch is shown in the figure below.
