If you're content to use a dryer with an inoperative switch so the machine thinks the door is closed all the time, just cut the connectors off the two wires to the switch, strip the ends, and connect the wires together, using a wirenut (hardware store item) or by soldering. The dead switch won't be a part of the circuit, so it can be removed or left in place.

A dryer with an inoperative switch will run continuously when the top-panel controls say "Start." That means that when you open the door of the running machine, the drum will keep rotating until you change the top-panel control settings to "Stop." This may result in clean clothes on the floor, or a damaged hand as the user reaches inside the turning drum.
