You are better off replacing the broken parts and fixing it correctly. By manually turning on the glow plugs you will burn them out in short order, if they are not already bad. If they dont come out in one piece, you may need to remove the head. Replace the ignition switch.
You certainly have a problem, checking th glow plugs is easy, 12 volts at the harness to each plug and resistance for the for the plugs, if they are bad it will read open circuit, as for toggling the circuit, bad idea, the original circuit cuts out when the plugs are glowing, without it you willl be constantly burning glow plugs,
