Switches fit single device (1 gang) outlet boxes. Program them to turn a device on and off at a set time and day. They’re often used with lamps and other small electrical loads.

24-hour switches repeat the same program daily. Position trippers around the clock dial to set on and off times.

Install these switches in a panel cutout and program them to turn a device on and off at a set time and day. Position trippers around the clock dial to set on and off times. As UL and C-UL Recognized Components that are also CE Marked, these switches meet American, Canadian, and European safety standards.

24-hour switches repeat the same program daily.

Control equipment with high currents such as landscape lighting, pumps, and heaters. Program these switches to turn a device on and off at a set time and day. Position trippers around the clock dial to set on and off times.

24-hour switches repeat the same program daily.

Switches with a day skipper can be programmed to skip operation for one to six days.

Additional trippers (sold separately) are sold in pairs that include one “on” tripper and one “off” tripper.

Rated NEMA 3R, these rain-tight switches protect against falling liquids and light splashing. They control equipment with high currents, such as landscape lighting, pumps, and heaters. Program them to turn a device on and off at a set time and day. Position trippers around the clock dial to set on and off times.

24-hour switches repeat the same program daily.

Switches with a day skipper can be programmed to skip operation for one to six days.

Additional trippers (sold separately) are sold in pairs that include one “on” tripper and one “off” tripper.

For precise control of high-current equipment such as landscape lighting, pumps, and heaters, these switches schedule on/off times to the exact minute. The seven-day timing cycle can perform a different program each day of the week. All have a day skipper that can suspend operation for one to six days. A backup battery maintains the program during a power outage.

Two-circuit switches can apply a different program to each circuit.

Rated NEMA 3R, these rain-tight switches protect against falling liquids and light splashing. More precise than other time and day switches, they program on/off times for equipment down to the exact minute. They control equipment with high currents, such as landscape lighting, pumps, and heaters. A backup battery maintains the program during a power outage.

24-hour switches repeat the same program daily.

Mount these switches to a flat surface or attach to DIN rail. More precise than other time and day switches, they program on/off times for equipment down to the exact minute. All have an override to bypass the programmed on/off settings. A backup battery maintains the program during a power outage.

24-hour switches repeat the same program daily. They control two circuits and can apply a different program to each circuit.

Control multiple timing functions from your electrical cabinet—these timer relays mount to 35 mm DIN rail (also known as DIN 3 rail), which is the most commonly used size. UL Listed, C-UL Listed, and CE Marked, these relays meet American, Canadian, and European safety standards.

Timer Relays with Delayed, Interval, Switch-On, and Repeat Cycles

With six different functions, these timer relays have a broad range of applications. Use them to precisely control machines such as conveyors, lighting systems, and electric motors.

The delayed start (delay-on-make) function allows you to set how long it takes for the relay to turn on after input voltage is applied. For example, a drill starts pumping lubricant immediately, but it does not start rotating until the set time has elapsed.

The delayed switch-on with delayed switch-off function uses a switch instead of input voltage. It allows you to set how long it takes the relay to turn on after a switch is turned on, and how long it will stay on after the switch is turned off. For example, a furnace turns on, but the fan doesn’t start pushing air through the vents until it has been heated. When the furnace turns off, the fan keeps blowing to circulate all the hot air.

The delayed switch-off (delay-on-break) function uses a switch instead of input voltage. When the switch is turned off, the relay remains on for a programmed amount of time before turning off. For example, a projector’s light is turned off with a switch, but its cooling fan continues to run for a set time.

The interval function uses input voltage to turn on the relay for a programmed amount of time. For example, when a part moving down a conveyor reaches a certain location, a cleaning spray comes on for a set time.

The switch-on (single-shot) function requires a switch to activate the relay, which stays on for the programmed amount of time. For example, lights in a storage room are turned on with a switch and stay on for a set time before turning off.

The repeat cycle function alternates between an on cycle and off cycle of equal durations until input voltage is removed. A common example would be a flashing light.

Timer Relays with Asymmetrical Repeat Cycles

Use these timer relays when your repeat cycles have different on- and off-cycle durations.

The asymmetrical repeat cycle alternates between different durations of on and off for as long as input voltage is applied. For example, a sprinkler system sprays in short bursts followed by longer rest periods, on and off until input voltage is removed.

The switch-on asymmetrical repeat cycle function is activated with a switch instead of input voltage. It could be used to turn on an electric motor for a short period and then turn it off for a longer rest period, repeating that pattern until the switch is turned off.

Timers with a calibration certificate traceable to NIST have been tested to NIST standards to ensure accuracy.

Timers with a memory function automatically return the display to the last programmed time. Good for timing repetitive intervals.
