Today, impulse relays are gaining popularity. This device is capable of controlling the turning on and off of the light. Thanks to this, it can easily reduce your energy costs. This device is today a stair switch. His work was created on the basis of a bistable or impulse relay. If you configure this device correctly, then it will independently turn on or off the lighting from several places at once.

The stair switch is a regular timer. Once configured, it will fire at regular intervals. For example, if you go up the stairs, then this process will not be noticed for more than one minute. That is why you can easily set the timer for one minute and after you climb the stairs, this switch will turn off the lights by itself.

An impulse relay is a device that will be controlled by impulses. To turn off this bistable relay, you need to apply a pulse that will do this. If you can combine this device with a timer, then you can easily control the light sources in the house.

In addition to the timer, this device also has another advantage, which includes the ability to control from different points. To do this, you will need to use a two-wire line. This process is straightforward as you no longer need to install walk-through switches in your home. has a similar scheme of work.

In our article, you will learn how to connect an impulse relay with your own hands.

Impulse relay and its device

In order for you to understand in detail and understand the device of the impulse relay, we decided to consider its operation on an impulse relay with a BIS-403 staircase machine. The body of this device is considered to be of high quality, but it is assembled without a single bolt. All the parts that are installed in it are connected using thermal glue. On the box provided by the manufacturer, you can see that this device should be installed in a back box.

This impulse relay primarily consists of an ST 78522 controller. It also has a 5 Volt voltage regulator. Also in its design you can find rectifiers and diodes.

This device should control the passage of current through a conventional relay. Thanks to the contacts that are installed in this relay, it is possible to determine the switching power. This device is capable of withstanding a load of 2 amperes. If your load is more than 0.5 kW, then you will need to install an additional contactor. For better protection, you will need to install a circuit breaker.

Installation and connection of an impulse relay

Now it's time to start connecting it. The impulse relay diagram will guide you through the installation process. The body of this device can be easily installed in the installation box. In order to connect the impulse relay correctly, you will need to additionally conduct a neutral wire. Thus, you get 4 wires. These include:

• Incoming phase.
• Neutral.
• Conclusion to buttons.
• Conclusion for power supply of light bulbs.

It is best to lead a cable with an extra core into the installation box. If you could not make out with this circuit, then here is a schematic diagram for connecting a pulse relay. In this diagram, you can immediately see that the buttons must also be connected in phase. has a similar scheme.

In this diagram, you see only two buttons, but their number may vary. You can connect 10 buttons to a maximum of one device. If you connect more, then you may experience false positives. In this case, you will need to locate the control wires further away from the power wires. You will also need to install an additional capacitor.

The manufacturers of this device claim that it can be installed in a junction box along with a switch.

Control and operation of the device

This switch is easy to use. Also, this device has a number of advantages, which include the ability to control from various points in the house. The impulse relay is by far the main competitor of pass-through switches. This device has an excellent timer that works great. In order to turn this device into continuous mode, you will need to press and hold the button.
