  • Threshold microswitch and a manufacturing method thereof
    Patent number: 5905241
    Abstract: A threshold microswitch includes a movable electrode, realizing an initial deflection by a difference in residual stresses; an upper electrode, provided at a fixed distance from the movable electrode; and a support mechanism, including a movable electrode support portion which supports both ends of the movable electrode such that a snap-through buckling phenomenon can be used when the movable electrode receives a threshold load. An upper electrode support portion supports the upper electrode such that switching with the movable electrode is realized when the same undergoes snap-through buckling.
