Why use a Contactor

Like most living organisms, plants need a period of darkness, so most growers set a timer to turn their grow lights on and off at specific times. However, grow lamps generate a large spike in electricity when switching on.

Without a contactor this electrical spike travels through the timer and is enough to cause the timer to burn-out, leaving the grow lights in the on or off position until you manually switch them.

With a contactor the power goes through the robust switching components of the contactor. The surge doesn’t go through the timer itself, so there’s no risk of burn-out and harming valuable pieces of equipment or even worse cause fires.
