To understand the difference between a pass-through switch and a standard one, in which the electrical circuit is interrupted in the usual way, you need to look at the switch from the reverse side.
The through switch has three contacts (as opposed to two contacts in ordinary ones) and a switching mechanism between them. Therefore, the through switch has some advantages, the main of which is the ability to control lighting lamps from different places in the apartment or office. Therefore, if you decide to buy a pass-through switch, it will be possible to connect it to the load line of several lighting devices and control them, for example, from different sides of a long corridor. The Livolo two-line through switch is equipped with four contacts inside and must be synchronized with the through switch located on the opposite side.
You can buy a pass-through switch based only on its appearance - from the outside, the switch may look like an ordinary one, and only if you look carefully, you can see a sign on the pass-through switch - an arrow down and up. The Livolo touch-through switches have the letter S.
