Abstract

An enhanced returning elasticity micro switch includes a base and a cap mounted thereon to form a housing compartment therebetween. The base is run through by a first pin and a second pin. The first pin has an anchor portion in the housing compartment to couple with a conductive member. The conductive member has a lower contact portion and swings when being pressed. The second pin has a first contact in the housing compartment. The first contact has an inclined surface connected to the lower contact portion during swing of the conductive member. The inclined surface is located at an elevation tapered towards the anchor portion. Hence the contact area between the conductive member and second pin increases, and adhesion force between the conductive member and second pin during power transmission decreases. Returning elasticity of the conductive member increases, and resistance against depression of the conductive member decreases.
