MOVABLE CONTACT MEMBER, MANUFACTURING METHOD FOR THE SAME AND SWITCH DEVICE USING THE MOVABLE CONTACT MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a movable contact member that is increased in lifetime, a manufacturing method for the same and a switch device using the movable contact member.SOLUTION: A movable contact member 10 is configured to have an outer shape having a short-side direction SD and a longitudinal direction LD, and has a swollen part 11 which swells in a dome-shape and is inversely operably, and plural leg portions 51 supporting the swollen part 11. The swollen part 11 has a protrusion part 11t which projects to the swelling side along the short-side direction SD in longitudinal-sectional view, and the protrusion part 11t extends in the longitudinal direction LD, and is provided at two places across the center portion in the short-side direction SD. A manufacturing method comprises a bending processing step of folding ta member so that the member protrudes to one side, thereby forming a bending-processed member, and a drawing step of drawing the bending-processed member so that the bending-processed member swells to one side in a dome-shape, thereby forming a drawing-processed member. A switch device is provided with a movable contact member 10, a first fixed contact member, a second fixed contact member, a first terminal portion and a second terminal portion.SELECTED DRAWING: Figure 1
