Timer Switch Operating Modes
Timer switches have different ways they work. Each way controls when your devices turn on or off. Knowing these ways helps you choose the best timer switch. The main ways are on-delay, off-delay, and interval. These ways let you set a schedule for your lights or appliances.
Here is a table that shows the most common ways and what they do:
Operating Mode | Description |
|---|---|
On-delay | Turns on after waiting a set time. |
Off-delay | Turns off after waiting when you stop input. |
Interval | Turns on and off at set times in a cycle. |
On-Delay Mode
On-delay mode waits before turning on your device. You press a button, and the timer starts counting. After the wait, the timer switch turns on your light or appliance.
