About Relays Contactors & Time Switches

A standard time switch is not robust enough to switch large wattage grow light directly. The switches inside of them cannot handle the current change at switch on or switch off. This often causes arcing which destroys the switch contacts.

Instead, a heavy duty switch is used to power the lights. A time switch simply controls the heavy duty switch which is called a relay or contactor.
