Light switches with delayed off time

Turning off the power grid at a specific time without the use of physical effort is not a myth, but a reality. Intelligent devices of this type have long been used in Europe, from home use to the optimization of complex industrial processes. A switch with an off timer, which is able to cut off the flow of electricity at the right time, will help to carry out the task.

Main characteristics of the device

A switch with a time relay makes it possible to efficiently and economically consume electrical energy, performing a resource-saving function. This smart device is equipped with an integrated software that allows users to set the parameters for the functioning of lighting and volatile devices.

The circuit breaker must meet the following characteristics:

• Have extremely long time parameters for which you can program it. The larger the time range, the more functions the device can perform.
• To have a high accuracy rate, taking into account the time intervals, to avoid errors in operation regarding the fact of relay actuation - an on / off device.
• Have small discreteness, high resistance against voltage fluctuations, operate in the range of 230 V with a current rating of 16A.
• Have sufficient functionality to set up various tasks to optimize the consumption of electrical resources. Support a different type of commutation.

Delayed breaker is a high-tech electronic device with a set of integrated programs. The base of the device consists of microcontrollers, relays, rectifier diode and resistors, which are needed to create intelligent lighting control.

Devices perform many functions:

• turn on and off lighting, both indoor and outdoor;
• monitor the modes of operation of volatile devices;
• maintain the microclimate in the rooms at a set level;
• guarantee the inclusion / shutdown of heating in automatic mode;
• turn on / off the fan and elements of the security system;
• regulate the modes of operation of advertising billboards;
• control the life support systems of large aquariums;
• manage irrigation and irrigation systems.

The automatic switch creates the effect of the presence of the home owners. This provides additional protection against unauthorized intrusions.

Features of devices with sleep timer

Delayed turn-off light switch is in demand in the field of domestic and industrial use. Such a device can be mounted on stairwells of apartment buildings, at the entrance to a cottage, in basements, offices or garages. Also, these switches are excellent for optimizing industrial processes when there is a need to set a clear time interval for the operation of specific devices.

A system of sensors, which are responsible for the reaction to external stimuli: cotton, the appearance of a figure, and so on, are installed in the body space of the switch.The timers of such devices can be mechanical or digital. The touch timer is more functional.

The settings for the circuit breaker are set by the following methods:

• By means of a control wheel or microswitches with several positions.
• By means of buttons on the front cover. The button can be physical or touch.
• Using a remote control or a tablet / smartphone - expensive models of switches support the function of remote access via the Internet.

The set time interval can be from a couple of seconds to several weeks. Some models can be programmed immediately for a year. Not only the switch, but also the socket can be intelligent. Such devices are indispensable when using boilers, electric heating and underfloor heating.

Instrument functions

The ability to turn off or turn on the light in time is the main task of smart switches. They also perform other functions, for example, you can program the device to turn on the heating system before the owners arrive. Also, the timer is configured to turn off appliances when residents leave the house.

Main areas of application for timer switches:

• control of automatic irrigation systems;
• collection / descent of water in terrariums and swimming pools;
• revision of the operation of aquarium devices - compressors, filters, etc.;
• security systems;
• street lighting of private houses.

The timer allows you to optimize the work of any electrical engineering that will function only at a set time.

Types of switches equipped with a timer

A switch with a delayed opening time can be of several types:

• A clockwork mechanism in security systems, when the lighting fixtures will be turned on to create the effect of presence. It can work both at a set time and in a chaotic manner.
• A device with an integrated motion sensor - designed to control street lighting and to equip lighting equipment in entrances or non-residential buildings. It turns on exclusively when motion is detected.
• Push-button switch - to start, you need to press the button, it turns off by itself, in accordance with the set time, which is programmed by the owner.

Installation is possible in premises such as a kitchen, bathroom, toilet or storage room.

By the principle of opening, the timer switch is divided into the following types:

• Devices with a mechanical timer - there are rotary and changeover types. Rotary switches are equipped with a rotary mechanism with contacts that connect / open at a specific toggle switch position. The scheme of operation of rocker switches is somewhat different. Such devices are equipped with 3 contact pairs and a metal plate, which is thrown over a specific pair, thereby closing it.
• Switches with an electronic timer - contacts are connected / opened when the button is pressed, after which the built-in relay is triggered. The settings and functions of such a device can be programmed.

Devices with an electronic timer are more functional and ergonomic. At the same time, they are highly sensitive to voltage drops, which reduces their service life.

Switch Modifications and Applications

Devices with a timer on / off allow you to control a variety of processes in the areas of power grids. They are actively used in private homes, apartments and in industry. On the market you can find a lot of switches from world brands that differ in design, principle of operation and technical characteristics.

How the watchdog timer works

The watchdog timer helps to protect the building from unauthorized entry.The device organizes the effect of the visual presence of the owners, which is important for those rooms that are left unattended for a long time. The built-in watchdog device periodically turns on / off the light in all rooms of the dwelling in the order set by the owner. From the street it will seem that someone is constantly in the house.

Light switch with motion sensor

The motion sensor switch is effective for installation in apartments and private houses. When people move around the room, an infrared-type sensor catches movement and gives a command to the relay to turn on the light. The device turns on the lighting smoothly, thanks to which the incandescent lamp serves its entire operational period. The sensitivity of the sensor can be set on almost every switch model. On individual fixtures, you can program a limit on the operating time of the lighting fixtures.

Push-button switch with timer

The push-button type electrical switch operates when the button is pressed mechanically. The light goes out or turns on in automatic mode after a specified period of time. Some devices can be programmed within a daily interval, while others can be programmed for the whole week at once. Such switches are installed, as a rule, in toilets, hallways, basements and garages.

Model with off timer for ventilation systems

Each private house or apartment is equipped with an exhaust ventilation system. For its rational use, you can install a light switch with a timer on and off the hood. It will cut off the power to the exhaust fan after the set time. This will maintain the optimal level of humidity in the premises.
