Passing switch - wiring diagram for 2 buttons , photos and videos

inclusion of such through-breakers in the e-mail / chain creates additional convenience for lighting control in private homes or large-sized buildings such as warehouses, manufacturing, and the like.Although for apartment owners these devices are of interest.As an option - the installation in a bedroom, which will turn off the lights of the other "points" located next to the bed.

But as a rule, mainly refers to products with the same key.This is the easiest option.We also deal with the fact that a switch is crossed by 2 keys, what is its feature and a circuit connecting with the device.

principle of action-through switch

Without basic knowledge about the device-through the switch on the two keys is unlikely to get clear on what scheme and how to connect it yourself.A more accurate name for this device, based on the characteristics of functioning - the switch, as at the time of pressing takes place transfer of the contact group and the chain from the "closed" ( "open") is transferred to the opposite.

Examination of the work it is advisable to start with one-button analog.Driving his connection is shown in Fig.

It can be seen that the phase wire is applied to only one device (№1).In the other (№2) and zero circuit switched lighting fixture.Both through-switch connected conductors.contacts can be flipped to control lighting.The lamp will light when their position in each of the items will be the same.This corresponds to the closure E / chain.Illuminator extinguished, provided in one of the devices to change the position of the key and, accordingly, the contact group.

Features dvuhklavishnyh devices

suited to the device №1 2 phase conductors.Accordingly, the keys - two.

Intermediate wires connecting the switches, not 2 and 4.

Connection passage switch 2 key

1. Connection contact groups together devices.
2. Joining lighting.
3. Connecting them neutral wire and lines of the pass-through device.
4. Check correctness of the assembly scheme.
5. Connect phase conductor.For any e / assembly work "power" (power) is supplied to the circuit in the least !!!

Connection Diagrams

Design of devices from different manufacturers may differ slightly.Therefore, further - only the general procedure for inclusion in the chain.Before attempting to install the purchased-through switch, you need to carefully examine its scheme, which is sure to be found in the accompanying documentation to any email / technical device.

author deliberately brought the same type of scheme with various graphic design.It gives the reader the opportunity to choose the one that it is more understandable.

options schemes in a manner

control is made from two points

scheme is the simplest. To avoid confusion with wires, it is better to use a cable with braided strands in color.How many should there be?Inputs - 2, from the outputs - 4, and make sure a couple of spares.Total - at least 8 of conductors.If the ground is provided, then plus 2 pieces.In the event of failure of any of the lines are much easier to produce 2 switching, than to engage in the replacement of cables (wires).

When operating in two directions diagram looks like:

Of the three points

This inclusion is somewhat more complicated and is used much less frequently.For example, on the stairs with several spans (for "sectional" off lighting).Or in the halls with more than two doors.In rooms where 1 is placed at the entrance doors, and the need to control the lighting of the two other points.In such cases, the need still crossover switch.It is not separately mounted - only in conjunction with passage.

turns out that nothing difficult in the passage connecting the device with 2 keys no.We just need to correctly identify where in the switchgear / box phase and zero (with the indicator).

Note:

Finally.If the wire (cable), just bought in a shop, it does not automatically mean that it has no defects.External damage is easy to notice, but the internal is not so simple.And breaks are - due to careless cable winding on a reel (drum) in the production, during transport, loading / unloading.

luck in the "automation" home lighting!
