Beschreibung
Zusammenfassung:	An operation member includes a body having an operating end and a coupling end, and a skirt member. The skirt member is arranged at the coupling end. The skirt member includes a base plate outwardly extending from the coupling end, a wall extending from the base plate, and a groove defined between the outer surface of the wall and the body. The electronic device includes a casing, an operation member, and a circuit module. The casing has portions defining an opening. The circuit module has a circuit board including a controller disposed thereon. The above-mentioned operation member is sleeved onto the controller and passes through the opening. The outer surface of the operation member and the opening define a gap therebetween. The groove is correspondingly arranged proximate to the gap to gather small particles entering the gap.
