Safely Runs Two Lights With Max Load of 13 Amps

Typical mains-powered electrical time-switches are not designed to switch the high currents required by hydroponic grow-lights. That's where contactors come in. You can use a contactor to switch the power output to multiple grow lights reliably and without risk.

How the Smart Gro Contactor Switch Works:

Most standard timers available today will fail if they are used to switch on and off a load such as a grow-light ballast. The Smart Gro Contactor relieves the timer of the job of switching the electrical power (which is what burns them out). Instead of using your timer to switch the power, your timer is used to switch the contactor and the contactor switches the power to your ballast. This contactor will safely and reliably turns on or off your lights when activated by your time-switch.

Maximum load: 13 amps


1 x contactor box with two sockets, and two power cables (one for the power and one for the timer)

Using the Contactor Switch:

Program your timer, set it to the correct time and insert it into a mains outlet. Insert the timer plug into the timer. Insert the plug marked 'Mains' into a separate mains outlet. Plug your ballast or ballasts into the output trailing socket on the contactor. Switch on the mains outlets. The contactor will now switch your lighting system on according to the program set on the timer. No more than two lights should be switched, with a load not exceeding 13 amps.
