A switch comprising:
- a wafer made of insulative material having a bottom and side walls forming a rectangular enclosure having longitudinal and lateral dimensions;
- a stopper wall disposed longitudinally in said rectangular enclosure and extending upright from the bottom of said wafer, said stopper wall having an upper portion with a central recess formed therein, said central recess being formed by a first upright side, an intermediate longitudinal portion at a recessed depth, and a second upright side opposite said first upright side;
- a pair of fixed contacts disposed on each side longitudinally in the bottom of said wafer;
- a movable element arranged longitudinally in the bottom of said wafer and laterally to one side of said stopper wall, said movable element having movable contacts on each end thereof, each movable contact being engageable with a respective one of said fixed contacts when said movable element is moved in one or the opposite longitudinal direction;
- an operation member for actuating said movable element which is pivotably mounted to the side walls on an upper portion of said wafer, said member having an upper operation end and a lower driving end which is pivotable in one or the opposite longitudinal directions;
- said lower driving end of said operation member having a driver portion engaged with said movable element, and a tapered abutting portion disposed swingably in said central recess of said stopper wall, said abutting portion being swingable with pivoting of said operation member so as to abut against said first and said second upright sides of said stopper wall in the respective longitudinal directions so as to define the limits of the pivoting movement of said operation member.
