Power Switch not working right

[FireGamer500]

Hello. I have a setup where a combinator is supplied power by a medium power pole. The pole is wired to a power switch, which in turn is wired to a circuit network. I've found that when the condition is false, and so the power switch should be off, I still get a trickle of power to the combinator. The power switch looks off. The pole shows no power. The combinator shows the blinking power symbol. But the line that shows how much power it's getting has just a small segment of red, and is still working. Is this a bug? Am I not getting something? I've had this happen multiple times. I'm certain nothing else is supplying power. If it were, then the combinator wouldn't be showing just a sliver of power, because all the poles show green. When I set a condition to turn the power switch on, the pole supplying power to the combinator goes full green. Any advice?

I just discovered it's not a problem with the power switch at all. I placed a combinator in an area with power, then deleted the pole supplying it power. It showed that slight bit of red. So, I'm going with a bug then right?
