If it has 4 terminals I don't think it could be a spst. spst stands for single pole single throw. The pole is how many things you're switching and throw is how many things you switch it to. A spst would have only two terminals. I think you need a dpst. Sounds like you're switching two things at once. Fuse to transformer and something to ground.


do you have a picture?
