Long gone are the days when all the switching circuits of electrical appliances were adjusted to the switching that was available. However, sometimes the switches and sockets were difficult to get. But today is a completely different time, there are a lot of functional and technically advanced devices on sale. You can make the wiring in such a way that turning appliances on and off will be as convenient as possible. In this article we will look at how to connect two switches to two light bulbs, and most importantly, we will determine in which cases it is reasonable to use such a circuit.
Advantages and options for using control circuits with two switches
Surely everyone knows the classic circuit, by which one lamp is connected. This requires the presence of one switch, which must be located in a convenient and accessible place. With it, the light in the rooms will turn on and off. Sometimes this is inconvenient, as the room may be too long, and most of the way you will go through the dark.
The article will discuss how to connect two switches to two light bulbs and control them from two, or even from three places at the same time. The main options for using control with two switches:
- In rooms and walk-through rooms, as well as in buildings with two entrances. It can be a barn, garages, farm buildings for animals or birds. If you set a switch at each entrance, you will not have to go through the dark every time to turn on the light or turn it off. After all, sometimes it happens that you go in one door, and go out through the opposite. Therefore, you need to consider how to connect two switches to two bulbs and control them from different places.
- This scheme will be very useful if you have long galleries, corridors, alleys and paths in the garden. You can use lighting when moving in almost any direction. You can turn it off immediately after you pass the site.
- Even in apartment buildings, you can install such a wiring. For example, in the entrance between the floors of a two-story house. In this case, the use of two switches will be both economical and convenient. But before you make two switches, you need to consult with your neighbors.
- The use of two switches in the bedroom will be very helpful. Put one switch at the entrance, and place the second near the bed. In this case, you will not need to get out of bed to turn on or off the light. This will be appreciated by the owners of houses in which the bedroom is quite large.
Features of using two switches
As can be seen from the connection diagram of the two switches given in the article, regardless of the position in which they are located, power is supplied to the lighting devices, and it is possible to turn it off. With conventional switches, this circuit cannot be implemented. You will have to purchase walk-throughs, which relatively recently appeared on the market.
Cross switches
The conventional switches that are used in most homes cannot be connected in such a way that they work as we need. You can, of course, cheat and install two double switches.
There are cross switches, but they are much more complex and can be used together with walk-throughs to control electrical devices from several points. They can be installed instead of a through-type switch, but they are more expensive.
Feed-through switches
Outward from simple switches, the checkpoint differs little in appearance. It has a case, three terminals for connecting wires, 1 or 2 keys. As for the cross switches, they have 4 terminals for connecting electrical wires. If it is necessary to control two groups of lamps on the same lamp, use only the passage switches with two keys.
Connecting a two-gang switch to two bulbs is not difficult. Such devices have 6 terminals for wiring. As for conventional switches, they have only 3 terminals. Cross-connects have 8 terminals for connecting wires.
As for the internal design features, a circuit consisting of two lines is connected to the passage switch. Regardless of the position of the key, one line will always be closed and the other open. It turns out that when you connect a two-gang switch to two bulbs, the circuit that passes through it does not open. This can be seen in the diagram given in the article.
Connecting Switches
It is possible to connect two pass-through switches in order to switch two electrical devices only in one single way, therefore no mistake can be made. But if you do not know how to connect two switches to two bulbs, it is better to refer to the circuit - it has certain difficulties. The rest of the article provides a diagram for connecting a single lamp.
This is a typical circuit, which shows that the passage switches are connected in series to the open circuit of the supply circuit, and the passage switches are connected with one two-wire wire. If you look closely at the circuit, you can see that the power can be opened and closed at any position of the switches.
Circuit assembly
The assembly of such schemes is not difficult. For switches, the input for 0 or phase is located on one side of the case, and two outputs on the other, so you can safely connect the two outputs, the order does not matter. Having connected switches, it is necessary to bring the rest of the wiring and connect the lamp. Be sure to use the device to automatically turn off the electricity - this will protect the circuit from short circuits.
