Is there a way of preventing a model from automatically snaapping to normal to ?

When orienting on a surface that I wish to work on I pick the surface and click sketch and the model automaticaly snaps to normal to on the new sketch. Is there a way of toggling this " autosnap/normal to " function on/off as I seem to spend a lot of time  re orienting the model again before I can work . There is probably a really simple answer to this but alas it is evading me .

I would be eternally grateful if anyone has the answer to this.

Thanks to all who respond.
