i have a gibson SG 61 re-issue

It has worked flawlessly up until now.

the problem is that whenever i put the switch to rythem on the 3 way switch it flicks back into the middle after a few seconds

any help would be great
How long have you had it? Switches eventually wear out.
ESP LTD EC-256 and a Fender Deluxe VM
^yeah... Sounds like the switch has worn out. They are cheap so just get a new one and be done with it.
Not taking any online orders.
its only about 5 months old, i wipe it down after every use, I never give it much rough handling i have other guitars for that.

Are there any other possibilities because im willing to fork out $20 or however much it costs but i would hate to depreciate the guitars value
