If there is ANY doubt about the switch, get a new one. There should also be a rubber boot protecting the START and GLO PLUG switches from moisture.

As @Capt Len posted, the switch should activate a solenoid, which should supply power to the glow plugs. However, the switch should also energize the start button to enable you to engage the starter. Many people have bypassed this feature for whatever justification they have managed to come up with. On my boat, I re-wired it to enable the switches to work as they should.
