Thanks to the time relay, you can seriously save funds. For example, it can be installed in the pantry, corridor or entrance, with one click you can include the light, and after a certain period of time it will turn off automatically. This time will be enough to find the subject in the storage room or just pass the site in the corridor. In this article we will tell you how to make a time relay with your own hands, consider step-by-step instructions and the simplest connection schemes.
How to make a time relay - the easiest option
We understand that the bulk of our readers is lovers. Therefore, they decided not to go into complex technical terms that can be introduced into a stupor. Especially for our subscribers, we found such a video, looking at which you can understand how to make a homemade timer to turn off the electricity.
We want to draw your attention that you should not have any difficulties, because the instruction is extremely simple for perception.
To make a time relay, we need the following materials:
As follows, the time relay connection scheme looks like:
Condensor here performs C1. The delay time of such a relay is 10 minutes. If we talk for other characteristics of whale, it boasts 1000 μF / 16 volts. The time is adjusted using a standard R1 resistor. The device is controlled by contacts, it is not necessary to do specifically for it, it can be collected, as shown on the layout.
Collect the time relay based on the NE 555 timer
The second time relay scheme is also elementary. But, for its assembly, we need a timer NE 555. This timer is designed to enable and disable various devices. Its scheme is as follows.
The main component of this device is a microcircuit, it is it that is used in the construction of the most popular electrical devices and timers. The microcircuit allows you to establish a load control using a special electromechanical relay. Therefore, you can adjust it to turn off and on light.

Management of such a timer is quite simple, you will find two buttons on the case:
- Start.
- Stop.
To start the time you need to click the "Start" button. If you need to return to the original condition, then click "Stop". Please note that the time interval is controlled by the R1 resistor and C1 condenser. It is from their nominal and depends on which the lamp and another lighting device will go out. You can set up time from two seconds to three minutes. Therefore, you can easily choose the best shutdown time. This model requires constant power from a 12 volt source.
