The 850 I just purchased has this light switch inside the housing. It activates by twisting clockwise. Does anyone have a photo of what the knob looked like? I will like to put a knob back on it. The shaft is twisted off where the knob once attached. I believe the switch is original because the two ears on the switch line up with two holes in the cover.
