There are ignition switches that will work. You may need to figure out the wiring. An ignition switch with a glow plug position usually goes for $60 to $80. I went to the auto parts store when my Mitsubishi ignition switch failed. I got a new generic automotive ignition switch for $5 or $10. Since it had no glow plug position I also purchased a heavy duty spring loaded momentary contact toggle switch to operate the glow plugs. I've been living happily ever after for the last ten or so years.
