Abstract:
A multiple-operation switch comprising:a lower case made of an insulating material having a recess with an open end positioned upwardly, said lower case having a recessed bottom area comprising a first fixed contact point disposed at a center portion thereof; a movable contact capable of a stepping action, said movable contact disposed in the recessed bottom area of said lower case such that said movable contact is movable between a first position in which said movable contact engages said first fixed contact point and a second position in which said movable contact does not engage said first fixed contact point; an upper case made of an insulating material for coupling with said lower case, said upper case having a through hole at the center thereof opposing the recessed bottom area of said lower case, said upper case having a bottom surface around the edge of the through hole formed as a spherical wall, said upper case having a plurality of second fixed contact points provided on the bottom surface thereof, said second fixed contact points positioned equidistant from the center of said through hole; a holding member being forced upwardly by a pressure member provided in said lower case; a movable contact body having a through hole in the center and provided around an outer periphery of an upper spherical portion with a conductive flange, said flange being disposed on said holding member and pressed upwardly via the holding member by a pressing force of the pressure member so that said upper spherical portion is engaged with the spherical wall of said upper case such that the movable contact body is able to make a tilting motion, and, when it is tilted, the flange makes contact with at least two of said second contact points; and an operating rod penetrating through the through hole of said movable contact body, said operating rod capable of vertical movement.
