Frequently Asked Questions
What is a timer switch?
What is a timer switch?
A timer switch is a control that automatically turns a light or fan on and off based on a set schedule or a specified countdown duration.
Can I use a timer switch for LED lights?
Can I use a timer switch for LED lights?
Yes. Most modern timer switches for lights are compatible with LED bulbs. However, some older mechanical models may have a minimum load requirement, so ensure your unit is rated for low-wattage LED use.
Do I need a neutral wire to install an in wall timer?
Do I need a neutral wire to install an in wall timer?
Many digital models require a neutral wire (white) for constant power. If your electrical box only has two wires plus a ground, look for a mechanical intermatic timer or a battery-powered digital version.
What is the difference between a countdown timer and a programmable timer?
What is the difference between a countdown timer and a programmable timer?
A countdown timer turns the load off after a set time (like 30 minutes). A programmable timer follows a 24-hour or 7-day clock to turn things on and off at specific times (like 6:00 PM).
Is there a timer that adjusts for sunset automatically?
Is there a timer that adjusts for sunset automatically?
Yes. An astronomical timer uses your location to track the sun, so you never have to manually adjust the time as the seasons change.
