A time switch is a device that automatically turns electrical circuits on and off at set times. It can be used for irrigation, lighting, ventilation, and more. It can be mechanical or electronic and is easy to use.
A time switch is a device that has a built-in mechanical or electronic timer that turns an electrical circuit on and off at certain times of day. Electric current is typically used to perform an activity that would otherwise be performed by a person. Time switches work in a variety of areas, such as irrigation or other water pumps, indoor or outdoor lighting, ventilation systems, and other devices that need to be turned on and off during the day. A time switch automatically performs these tasks so that a person does not have to remember to do it or have to physically operate a switch at certain times each day.
A time switch fits into an electrical outlet between the power plug and the actual outlet. This arrangement allows the device or devices to receive power for a specified time. There is usually a cover page that contains instructions on how to use the time switch and the rating limits for the time switch.
The time switch has a dial that can be set to the correct time. This motorized dial keeps time, just like a clock or watch. As the dial progresses, activate the mechanisms to turn the device on and off at the right time. These mechanisms are located on the face of the dial and are usually bolted down at the desired times. Some units allow the user to set the switch to turn on and off multiple times throughout the day.
There are also electronic versions that can be programmed to turn on and off at certain times. Mechanical time switches often allow for a limited number of time settings, but electronic versions typically allow for an unlimited number of times a device is turned on and off each day. Some electronic time switches, however, may need to be reprogrammed after losing connection to an electrical current, such as when there is a power outage or when a switch is unplugged for any reason.
