Noctigon KR4 - Sticky Tail E-Switch

I’ve purchased 3 KR4’s this year and all are great except one of the tail e-switches is very sticky. If it sits a while I can hardly press the switch. After that initial press it gets easier, but still sticky. I am waiting for Hank to respond to my email.

Anyone know of a fix for this?

I don’t have this problem with my KR4, but I suppose you could disassemble the switch. Maybe use a polishing cloth on the edge of the button’s socket.
