I'd swap left and right flipper switch. Could be the new one has an issue like the old one.

See if the problem moves.

I doubt it.

You mean like where the points on the leaf blade strike each other aren't making a good circuit ?

I'd suspect the points aren't making good contact with the blade they are on. Poor manufacturing.

I'd solder the little bastards to the blade and be done with it.

Micro mini switch or leaf blade ? If leaf blade, then they are blade type.

And your little silver tops ( the two contacts ) aren't making good electrical to the blade they are hooked to.

To try and explain better. This is a leaf blade switch.

Red arrow points to one leaf blade.

Yellow arrow points to contacts.

White arrow points to where the contacts are affixed onto the leaf blade.

Now when you push them together hard and they work, hints at a poor connection between the contact and leaf blade they are affixed to.

Grab a meter and check continuity of each transistor leg away from the repair area. To be sure you don't have a cracked or broken trace.
