Brake Light Switch

Good morning,

Can anyone share any insight on how to remove the Stop Light Switch? I looked on YouTube and none of the older models are shown.I don't have brake lights, and with my test light I am getting ho on both terminals of the switch at all times. I am thinking that should bot be, and it is an indication of a bad switch, broken rubber stop or something. I can turn the cylinder of the switch and I can see what looks like a nub on the outside, like it would line up with a slot and slide out, but tuning does not match any slot. The new switches at the auto parts stores are all threaded plastic cylinders, so that is easy to assemble. I just can't figure removal of the original one out.
