Generally it isn't the switch that would be at fault. The mechanism itself has to ride on a rail or something and those get dried up oil in there and don't want to slide. I'm not sure what model you said you have. Start a new thread on the vintage sewing machine area or over at the Victorian sweatshop forum. Shoot a pic of the inside top of your machine focusing on the stitch selection mechanism. I had a Bernina that was frozen up but good and left it in the car in the summer time which is a no no but all that heat did make it move. But then the oil dried back out and I had to clean it with some solvent and reoil.
