I'm trying to convert some leaf switches (with diodes on them) to microswitches on an 80s game but not really familiar with microswitches. I bought a couple of new ones to experiment with that are made for rollovers on today's games marked NC/NO/NC, so it's like a double throw where depending on the lugs used, the actuator can either complete the circuit when closed, or open it. Has diode across the outer lugs.

So how do I (or can I?) connect my existing two leaf switch wires to this? Same as old switch where one wire goes to lug with unbanded diode end, other wire goes to the center lug? I'm not sure because on the leaf switches the unbanded diode end isn't connected to the switch blades itself, only to a mounting lug for one of the wires. Or am I just trying to use the wrong switch? Thanks!

Okay I found out elsewhere in here that I need to clip the unbanded diode end off and use that end to connect directly to the 'lug' wire, other wire goes to center lug, with the other outer lug now unused. Solved!

My switches have various color wires, not necessarily green and white(?) It's the drop targets on my BK. I was going by someone who converted a bunch in a Black Knight and used similar 3-lug switches on some rollovers but they didn't have diodes already on them. One wire was connected to a new diode, other diode end connected to one lug, other wire to another lug, with one outer lug unused.

So - I can connect the wire that previously went to the old switch's unbanded diode lug to the new lug which has the unbanded diode end on it, and the other end to the center lug?

Okay I ran alligator wires from the existing switch's two wires to the new switch's center lug and the outer lug with unbanded diode end and yup, by golly it works. So I dunno if the other BK guy was using 3-lug switches that were actually different or what. Glad I don't have to snip the diode and have it hanging out there like that. Thanks!

You mean the wires? Many different ones but I think each 3 bank does have one green wire (striped different colors) which is daisy chained to the next two in that bank so that's why some don't actually have a green wire on the switch, so I just went by the diode orientation on the switch lugs.

Thanks for those because I now know I got lucky picking the correct outer lug. The locking washers that secure the switch to the mount were covering up half of the ID markings for the outer lugs and I thought the C on one end was just a chopped off "NC" but it was only a C, the common lug. So I was in error saying it was marked NC/NO/NC, it was NC/NO/C.
