Installation of a bipolar switch with 220V lamp

Bipolar switch, how to install?

Do you know what a switch is? Do you know the bipolar switch? Do you know what electrical circuit it is used for? How to choose between 220V, 127V or bivolt lamp? In this article we will answer these questions, show the types of switches and demonstrate how to install a lamp with a bipolar switch, come on guys!

What is a switch?

As described in its name, a switch is a component that has the function of exercising control, interrupting or restoring the passage of electric current according to the position in which it was placed, open or closed.

The importance of a switch, whatever type it may be, is something that nobody can doubt nowadays! Because for many things that turn on and off, a switch is needed to perform that function.

The switch can control many loads such as ceiling fans, light bulbs, some home appliances and small motors. Therefore, it works as follows: when activated, it closes the circuit and allows the passage of electric current to the load (device receiving energy). And when it is turned off, it opens the circuit and interrupts the flow of current, turning off the load.

The current that will pass through the switch must be well dimensioned and cannot exceed 10A (amps), which is the current supported by most switches, with some exceptions of switches that support up to 15A.

What are the types of switches?

Currently there are numerous types of switches with different characteristics and uses, among these numerous types of switches we can mention the main ones that are:

Single switch (can be single, double, triple or multiple)

Bipolar switch

Parallel Switch (Three Way)

Intermediate Switch (Four Way)

Pushbutton Switch

As said at the beginning, in this article we will focus on the bipolar switch!

What is a bipolar switch?

The bipolar switch, like the others, is an electrical component that opens and closes circuits through its open or closed position.

Its use is made in circuits that have two phases, whether 220V or not, and in other types of circuit such as direct current circuits with different voltages. It has four posts that are used to connect the cables.

Installing a two-pole switch is not very difficult, the procedure is actually quite simple! What is needed is attention, as the wrong connection can compromise the functioning of the circuit. The two-pole switch can be used for many purposes, such as connecting low-current two-phase electric motors.

How to install lamp with bipolar switch

We will use as an example the installation of a lamp with a bipolar switch. To begin with we must choose the lamp, but which one to choose? The two-pole switch is used in two-phase circuits. So the ideal lamps are 220V lamps or bivolt lamps.

The first step in this installation is to identify the phase cables using a multimeter or test switch. Then turn off the power to the circuit by turning off the circuit breaker or the main circuit breaker so that no electrical accident occurs.

With the power off, run the phase cables to the bipolar switch. If you think that to make the connection you just need to connect the cables to the upper terminals and leave them on the lower terminals, know that this way will be wrong and will not work.

The image below shows the incorrect way some people connect the cables in a bipolar switch.

The correct way to connect the cables in a bipolar switch is to connect the phase cables to the center terminals and exit with the return cables from the side terminals. The input and output drawings are usually numbered on the switch body. The image below shows the correct way to connect the cables on a two-pole switch.

After switching on the switch, take the return wires to the lamp and connect one wire to the center post of the receptacle and the other wire to the side post of the receptacle.

With these steps performed correctly, now it's just a matter of checking the connection, reconnecting the power and checking the operation of the circuit. After that, your installation will be ready for use.
