Feedthrough switches: connection scheme from 2 places to two lamps

Pass-through switches are installed in junction boxes. Many models are produced with a two-button switch. If necessary, you can install several devices in the same network. If we consider a circuit with two lamps, then the connection is via the transceiver. The type of cable, box and switch is taken into account. In order to understand this question in detail, it is recommended that you familiarize yourself with the connection diagrams.

Scheme with one box

The circuit of connection of the pass-through switch with 2 places (the photo is shown below) assumes application of the expander. If we consider contact switches, then they can be installed with wire adapters. In this case, the trigger is applied with a winding. The first contact of the switch goes to the zero phase. The resistance on the plate should be 55 ohms. The second switch is connected directly through the expander. Also it should be noted that the block is preliminary important to clean. The second contact is connected to the block winding.

Scheme with two boxes

The circuit for connecting the pass-through switch from 2 places to two lamps has a controller. The first switch is mounted in the zero phase. In this case, contacts of the second order are closed on the plate. The second switch is installed through the expander. It should also be noted that the resistance on the controller must be at least 30 ohms. Sometimes an insulator can produce breakdowns. In such cases, electricians install an additional plate.

If we consider three-button loop-through switches, the connection scheme of 2 places has a double controller. Only one expander is required. The upper contacts are pumped in the first phase, and the resistance on the plate is 35 ohms. If we consider a standard two-button type switch, it should be compatible with the expander.

Application of a two-wire cable

Through a two-wire cable, various feedthrough switches can be installed. The connection scheme for two lamps involves the use of a dipole transceiver. Directly connect the junction box carefully. The switch can be mounted on the adapter. Basically it is applied with a lining. The isolator in this case is installed last. It should also be noted that the triode will require a linear type. If one-knob bushing switches are considered, the connection plan of 2 places consists of a contactor and a filter. The upper contacts are clamped onto the plate. The bottom wires must go to the first phase.

Connection via three-core cable

Using a three-core cable, it is easy to install a through-switch. The connection scheme from 2 places to two lamps has two expanders. The first switch is installed near the connector block. The upper contacts of the device go to the zero phase. On the contactor, it is important to check the resistance immediately. This parameter averages 5 ohms. If we consider the junction boxes, then the contactor can be used with an analog filter. The lower contacts of the device are closed in the second phase.

The insulation must be under the box. Also it should be noted that there may be problems with switching on the lamp. In such a situation, it is recommended to check the insulation of the wire from the switch. The resistance on the controller plate averages 30 ohms. If two-button loop-through switches are considered, the connection scheme of 2 places has contacts that close from the bottom row. The output wire from the plate goes through the zero phase. The resistance on the block is, on average, 45 ohms. If you consider switches on three buttons, then they can be mounted on expanders. In this case, the controllers are of different conductivity. Specialists are advised to immediately check the resistance level before connecting.

Using a four-wire cable

The circuit of connection of the pass-through switch with 2 places through a four-wire cable has two expanders and one contactor. If we consider a simple model, the expander is installed together with the insulation. It should also be noted that the switch is mounted on the lining. The top contacts of the device are immediately connected to the zero phase. Beforehand, the plate must be checked by a tester. In some cases, the closure is malfunctioning.

At the same time, the resistance is 45 ohms. The contactor for switches can be used with winding. Adapters for blocks are used only of low-resistance type. Sometimes contactors are used with filters. If necessary, the wire from the expander can be isolated. The triode in the block must be located at the bottom. The second switch must be connected via the controller. If there are problems with current breaking, then a lining is installed.

Connection with remote unit

The circuit of connection of the pass-through switch with 2 places with the remote unit has one controller of wire type. If we consider switches for two buttons, then the connecting contacts go to the first phase. The plate must first be checked by a tester. In some cases, the unit needs isolation. The second switch must be connected via the expander. It should also be noted that the contactor must be cleaned. The resistance on it is on average 45 ohms. If you use an adjustable expander, the contacts from the controller are closed in the zero phase. The triode must be kept under insulation.

In addition, we need to consider a circuit with switches for three buttons. The expander for these purposes is suitable for low-resistance type. The first switch is connected via the controller. The upper contacts of the elements go to the second phase. Another switch is allowed to be connected only through the cover plate. In this case, the connection block must be checked immediately by the tester. The upper contacts of the second switch are closed in the zero phase.

Using a discrete switch

The circuit of connection from 2 places (passage switches of discrete type) assumes application of one expander. Experts recommend that controllers be used only on the plates. It is also important to note that interlocks with different conductivity are suitable for connection. Considering the switches on two buttons, it is important to note that the connecting contacts always go to the first phase. In some cases, the expander may malfunction. This is due to the increase in polarity in the circuit. To solve this problem, filters are applied.

Examination of connecting blocks with dinistor

The circuit of connection from 2 places (pass-through switches) with dinistors has closing contacts and the controller. If you talk about switches for two buttons, then the expander is used with a lining, and the resistance on the plate should be at least 55 ohms. In some cases, two contactors are used. All this is necessary in order not to waste time on isolation. The controller must be installed behind the adapter.

In some cases, the expander is used with one output. The upper contacts of the first switch are connected in the first phase. It should also be noted that the switch must be located next to the junction box. However, it is attached only through the expander. If we talk about simple one-button loop-through switches, the connection scheme of 2 places has contacts that are closed in the second phase, and the resistance is no more than 45 ohms. Triggers in this case are not used. If we talk about schemes for two expanders, then the first switch is always mounted with a thyristor.

Application of an integral expander

Integral expanders are connected to a wiring box. The expander in this case is mounted behind the adapter. Two-button switches are installed with a lining. It should also be noted that the filters use low conductivity. The upper contacts of the switch always close in the zero phase. It should also be noted that the outlet of the expander is important to clean thoroughly.

The lower contacts of the first switch go to the second phase. The conductor must be under the insulator. Trigger for the standard box is suitable with an overlay. The second switch in the circuit closes at the output of the controller. Its upper contacts go to the first phase. Isolator should be used only on discharge amplifiers.
