Time and Day Activated Switches

7-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.

7-Day Timing Cycle—Seven-day switches can perform a different program each day of the week.

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

Smart Time and Day Activated Switches

Use your smart phone to turn equipment on and off at a set time and day. These switches connect to your phone via NFC (near field communication) and work with a free app to set schedules, adjust settings, and save programs. They can perform a different program each day of the week, and they compensate for leap year and daylight savings time. You can remotely apply programs across compatible switches, so it’s easy to reprogram lighting or equipment in large facilities. These switches mount to a flat surface or attach to DIN rail.

Preventative Maintenance and Inspection Indicators

Mount these indicators to your equipment, and their bright LED will catch your attention when it’s time for maintenance or inspection. They’re commonly used to keep track of maintenance on production lines and HVAC systems, or paired with inspection tags on fire extinguishers and eye wash stations.

When first set, these indicators flash a dark green and then a light green color every two minutes. As a scheduled inspection approaches, they flash a yellow light every 10 seconds. And when an inspection is past due, they blink red every two seconds. Reset indicators to start the countdown again. They meet IP65, so they seal out dust and low-pressure washdowns.
