To get the switch out, you need to compress the fingers at the ends of the switch that hold it into the panel. I have used a fine jewelers screwdriver from the top. Push straight in between the switch and the panel and then lever the tip toward the switch body while putting some upward pressure on the switch. Get one end up and repeat if necessary on the other. If you can get the panel up, it is easier to compress them from the bottom.
Once you have the switch out and can get to the terminals on the bottom, just use a piece of metal to jump the terminals. A broad screwdriver should work. You shouldn't have to rework the switch to reset the ABS.
