I think the knob should just pull off, then unscrew the retaining collar to release the switch? I sure someone else will know for sure.

The yellow tab on the back of the switch, turn it. The back of the switch will come off.

Thanks Louis! It came off I was thinking it had something to do with the yellow thing..
