Abstract
The utility model discloses a kind of anti-misoperation thin film switch key, specifically related to thin film switch key technical field, including panel body, three-dimensional rubber key and sliding type protective cover, three-dimensional rubber key is set in the upper end surface of panel body, sliding type protective cover is installed in the inner chamber of movable limiting frame;By sliding type protective cover using sliding slot and limit pin form sliding guide rail structure, cover when can completely shield panel, physically isolate panel and external environment, so that external object cannot directly contact key surface, even if exerting pressure, force will be borne by protective cover, not transmitted to key, can continue to protect switch key, by three-dimensional rubber key, touchpad is lifted, when external force does not make key produce enough deformation, can prevent key bottom conductive layer and circuit board contact, avoid the false signal output caused by virtual touch, need exert greater vertical pressure to make corrugated structure compression to trigger state.
