Could be the switch. Could be the wiring, but either way contact is being made between the switch wires.
Put a meter across the 2 terminals of the switch ( wires off) and if you have continuity then the switch is jammed in the on position. If the switch is working properly then follow the wiring to find the short circuit.
You can have a look at the exploded diagram for your cassette on the thetford site just look for the spare parts page and it will come up with an exploded diagram giving you the layout of the parts.
