Master Flush 8700 part needed

Having problems with the half bath that has a handle to flush. You push down to flush and pull up to fill the tank with extra water. Having a hard time with the flush and want to order a new 12 volt flush handle switch which seems like a $20 part but they only sell it as an entire kit, handle and all. Don't need all of it, seems silly. They want $220 or more.

Does anyone know about this part and have a work around. Is there a way to "clean" the switch? Any suggestions would be appreciated. I need part 3 in the pic but they now require you to buy 3,4, and 5.

I believe the part number according to the full diagram I have, is Masterflush Dometic # 385311703

Is this it? Still pretty expensive for as you say "a $20 part," but here it is directly through Ardemco, $90.30:
