I switched to the Cermark switches a few years ago, now that's all I use.
There prices are reasonable, and they are close by. Most of the time I get
stuff next day from them. I had a Futaba switch fail on me. They were
soggy feeling....not crisp. I threw out two new ones, the bad one, and the
Hitech switches, and got a bunch of the Cermark's. They have the best price
( I think ) on the extensions and Y's too.

I had three Hitech's that would not charge through the charging lead. []
Try the dielectric grease in the connectors....mash a bit into the female side.

FBD.
