M5 key / ignition switch options

Anyone have any good suggestions for a key / ignition switch for an M5? It is my loader tractor so it doesn't have to be original, just wondering what people have used. I have seen some serviceable switches that have a knob not a key and are 4 position, but the hole has to be drilled out.
 
I always just take apart and clean. Other option is drill a small hole in side and use electronic contact cleaner spray. Failure is from moisture getting in. Usually copper contacts green. See odd one that is burnt from light position.
 
When I rewired my M 5 diesel I used a toggle switch to turn power on and off and another toggle switch for the lights.
 
Do you have some pictures on how you took them apart since these are crimped together?
 
I just use bench grinder. Go around lip until wafer free. Hold in place an open slowly as springs will fly. Clean and reseal.
 
I don't grind too much. Usually they kinda snap back together. Usually just tap in sides to secure and wrap with tape. Not a sealed unit,long as board secure. You could glue. Hole in side an fill with contact cleaner used to work but no good cleaner anymore like we used in TV tuners.
 
Any ideas on what kind of glue to use? Have 3 apart but only one has decent contacts in it.
 
Contacts burnt? Any decent glue or sealant. I wrap with tape after. Doesn't take much to hold bard in place.
