But to be honest, we know damn all about grass cutters.
We may not know anything about riding mowers, but we are refrigeration technicians, and we know more about problem solving than any other mechanical/electrical occupation combined, and we just love to solve problems

So I have spent the last few hours googling the electrical diagrams for the "John Deere GX345" and anything that can be called a "safety switch" that I can find is the "operator presence switch" that is under the seat.

These can be bought through E-bay for cheap:

There are also numerous youtube videoes showing how to disable it.

But to answer dannyr's original question, if it is the seat switch that is the problem, any ON/OFF switch would work, and if you are going to replace a faulty "operator present" switch, I don't think the switch you mentioned would work, as it's a proximity switch, and as long as the seat is down, it will say that everything is ok.

The "operator present switch" says that "operator is sitting in the seat" so, I would go for OEM parts on this one
