Strange light switch operation

[rbrady]

I had a light switch that CONSISTENTLY worked every other time. I tried it about 20 times and every other time the light would come on. I could wiggle the switch and it would not flicker, like an intermittent switch.
It even worked as described when demonstated to the realtor (that's the real test - when you tell someone and it actually does what you describe )

Any ideas?

I had a remote (radio transmitter type switch) that functioned like that.

You had to wait between operations of the switch.

Must admit I would have removed the plate to look.

Visual is nice as a theory but......
