I have been using a clip on guitar tuner for a few years now but I still don't know what the switch at the side is for - it has an option for a flat symbol of a sharp symbol. Can anyone help?

Could be many things, but I would guess that this is to change the frequency you tune to.
Standard concert pitch is A=440Hz, but for reasons, you might want to tune sharp or flat from that standard, and those buttons (probably) allow you to do that.

3Practical test - if pressing + makes it say 441, 442, 443... then you're probably right– TetsujinJan 16, 2019 at 18:21

These buttons likely allow you to calibrate the tuner itself to a fixed pitch instrument like a piano or pipe organ, so that your guitar will sound in tune with the piano when the guitar is tuned with that device. Jan 16, 2019 at 19:06
