Unlikely the speed selector has failed. Much more likely the windings have failed. You're looking at a new pump.

You might be lucky. A merchants may still have these on the shelves but it's more likely you're going to be fitting a smart pump.

More expensive initially but it'll save you money in the long run.

pump works if you put pressure on the switch ie push the white slotted switch with a screwdriver

Ok. Still not a replaceable part unfortunately, you're still looking at a new pump.
