Digital timers keep track of timing, trigger an action, start timing once triggered by an action, and both. Some products are programmable while of others may be fixed at a set internal time or function.

Digital timers are used in an array of applications, such as controlling the lighting of the systems, watering schedules for gardens, and even in the circuits diagram of security alarm systems. By using one of these devices, you can automate your processes, save time, or conserve energy.

Mechanical timers are more reliable or durable but are bulkier than their digital counterparts. They could handle higher electrical loads and tend to be larger than digital timers. Digital timers, on the other hand, could be installed on the wall and are less noticeable.

Unlike that of a mechanical time switch, the settings on a digital timer are typically done via buttons or an LCD display, allowing you to set up precise intervals. Many models allow you to set up multiple time intervals at once and could be programmed for weeks or months in advance.

They both work the same way or can perform the same functions. Mechanical timers tend to be larger, last longer, or can handle more electrical load than a digital timer; however, they also tend to be designed as large, grey, metal boxes, that may stick out quite a bit in your home décor.
