I have 4 identical spots on a single extension cord around the outside of the room, plugged into an outlet on a light switch. They're pretty cheap 8" tall short spots with those rotating switches.

All high ef LEDs. 2 120v 14W, 2 120v 7W. This should be a very low total load for an outlet, correct?

When I flick the switch on, the last spot on the cord flicks on, and then back off. About 70% of the time. I have to dig up the cord and rotate the switch a few times, and it turns on on the 3rd - 5th rotation.

I thought one was faulty, so I switched it with another to test it, and sure enough, the 'broken' one works fine in position 3, and the one I moved to the 4th position is doing it now!

Is there such a thing as 'electricity hammer', similar to water hammer? So it's a long cord and it's creating a surge that is popping the switch into the off position?

Is it safe to cut out the switch and connect with twist on connectors? Is there a safer way to do this?

Or is the flicking off a sign something dangerous is happening? Thanks in advance!!!
