About Timing Functions

24-Hour Timing Cycle

Seven-Day Timing Cycle

Program these switches to turn a device on and off at a set time and day. They have a three-prong outlet to plug devices directly into the switch. Use with lamps and other small electrical loads. All have an override to bypass the programmed on/off settings.

24-hour switches repeat the same program daily.

Seven-day switches can perform a different program each day of the week.

Switches with trippers are programmed by setting on and off times by positioning trippers around the clock dial.

Switches with astronomical timing can be set to turn lights on and off based on sunrise and sunset.

Outdoor Time and Day Activated Switches

24-Hour Timing Cycle

Seven-Day Timing Cycle

Designed to work with landscape lighting and filter pumps, these switches turn equipment on and off at a set time and day. They control two devices at once, and have three-prong outlets to plug devices directly into the switch. All have an override to bypass the programmed on/off settings.

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

Seven-day switches can perform a different program each day of the week. They have astronomical timing that can be set to turn lights on and off based on sunrise and sunset.

Switches with light sensor control allow one device to be controlled by the presence or absence of light.

NEMA 3R rated switches are protected against falling liquids and light splashing.

Outlet-Box-Mount Time and Day Activated Switches

24-Hour Timing Cycle

Seven-Day Timing Cycle

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.

Seven-day switches can perform a different program each day of the week. Use the astronomical timing to turn lights on and off based on sunrise and sunset; this option can be used independently or in combination with timed programming.

Seven-day switches can perform a different program each day of the week.

Seven-day/365-day switches can perform a different program each day of the week or year, and compensate for leap year and daylight savings time. Override regular programming for up to 99 holidays for any length of time. They can also be used to activate equipment such as bells and signals for just a few seconds.

Switches with astronomical timing can be set to turn lights on and off based on sunrise and sunset.

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

Wall-Mount Timer Switches

Use these switches in place of standard wall switches to automatically turn electrical equipment on or off after a set interval of time. They’re often used with lights.

Switches with override can bypass the automatic shut-off.

Set switches with beep and light signals to alert when the timer is almost done; the signals can also be turned off.

Switches with set time recall retain the last setting; hold the button down to restart the timer with that setting.

Timers

Style Q timers have an extra-loud alarm that can be heard over background noise in a typical manufacturing environment.

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.
