What is an electronic timer? Electronic timers:
- Process time
- Activate processes by switching the circuit on and off
- Are powered by electricity (typically AC)
While they have the above three things in common, they vary widely by format, style and application. Some are analog timers, while others are digital timers, for example. Some can switch processes on or off at multiple intervals. Some serve commercial or industrial applications, while others are for the consumer. For a better perspective, let’s look at a few different types of timers.
Electromechanical Timers
Mechanical timers have been around a long time. These are the tried and true analog switch timers used widely for years to activate electrical circuits over prescribed times and durations. They’re driven by a motor that rotates a wheel. When the wheel comes in contact with a metal insert called a “tripper,” the electrical circuit is turned on or off. To activate multiple on/off times, additional trippers must be purchased. Because this type of electronic timer is analog, electromechanical timers must be updated manually to accommodate daylight savings time changes. These products time the activation of switches in consumer, commercial and industrial settings. Use electronic timers for lights, pool pumps, appliances, water heaters, and various other process cycles.

Electronic Timers
Electronic timers are the updated digital cousin of the electromechanical timer. So how do electronic timers work? All have a small set of programming buttons as well as some memory. They can be programmed for on/off switching of a circuit over multiple days and times, and they can be programmed to adjust automatically for daylight savings. Applications for this type of electronic timer are the same as electromechanical timers.

Specialty electronic timers
In addition to the above standard electric timers, other electronic timers are designed for specific purposes, among them:
- Wall Switch Timers - replace a manual wall switch with this automatic switching override.
- Plug-In Timers - plug these into an existing wall socket, then plug your device into the timer. Program the plug-in timer to switch power to your device, turning it on or off as desired.
- Hose Sprinkler Timers - these timers make it easy to comply with conservation and water use restriction schedules for the irrigation of lawns, shrubs and gardens.
- Defrost Timers - this type of electronic timer is used in commercial refrigeration systems to control fans and condensers and to help avoid frost build up on evaporator coils.

While the question of how to set an electronic timer depends primarily on whether it is digital or analog, all timers supplied by Zoro are designed to switch a circuit on or off at a predetermined time. Use these timers to control pool pumps, water heaters, irrigation pumps, HVAC condenser fan motors and more.
