There is, but not “mandatory”. On mine, the starter would not start if the key is not in the “glow plug” position. This is the factory set-up.
Some people change this to a separate “pre-heat” switch and no interlock. The advantage is that you don’t have voltage drop on the glow plugs, when you crank the engine. If the battery is weak, this could be a plus. Btw. I am not advocating the change; only pointing out that there are two schools of thought.

Pull the switch, take it to their parts guy. He will probably have a replacement. Otherwise, it should be fairly available online. I'm not familiar with that exact switch but you're probably looking for a 4 position ignition switch. The 4 positions should be : Off, Ign, Start and Pre-heat or Heat. A switch with the correct order of the positions is what you're looking for. Dennis C.

Can people on this list suggest where to purchase a replacement switch? It has several positions: off, on, glow plugs only, start. The switch now doesn’t automatically remove power from the glow plugs when the key is released. The rest of the panel is still working well (temperature and RPM gauges) so I would rather replace just the switch.
