I am going to install low voltage lights for the front of the house and a low voltage flood over the driveway that has a basketball hoop. I was hoping to only turn on the flood light when I want it for basketball -- so was hoping to put it on a switch. Can I just use a simple toggle switch and install it on the transformer? Not sure how to wire it exactly -- was thinking I would just take the wire connected to the 12V/15V clamp of transformer and interrupt it at the switch but keep the COM wire intact. Would that work? Any other advice?
I have used a switch to on/off the lights over a grill. I just found a convenient location for the switch and installed a 'switch loop'. Cut one strand of the main wire to the light on the B'ball hoop, connect a 2-strand wire, one leg to each of the cut lines. Run that wire to the switch location, install the wire to each side of a simple single pole switch, put it in conduit if necessary and an outdoor switch box, and voila, here comes LeBron!
Checking in here to see what you guys did. I have one light I want to isolate. Can I just do a low voltage switch on that one line?
For controlling a single 12V fixture, a 12V toggle switch/relay on the wire run would be the easiest, most convenient method likely. One thing to take note of is - if the relay/switch is not properly stopping the flow of electricity completely to where the LED bulb/board is still receiving low levels of residual voltage, it could cause damage/unpredictable results overtime. A voltmeter would be handy for double-checking the current.
