Abstract
The switch body includes: a wiring substrate where first to fourth fixed contact members are formed; and a movable contact member including a pressure receiving part opposite from the second fixed contact member, a first outer edge facing the first fixed contact member, and a second outer edge facing the third fixed contact member. The fourth fixed contact member is formed in a region outside a projection region being a projection of the movable contact member on the wiring substrate and is in a position facing the first outer edge when the second outer edge is moved to a region where the second fixed contact member is formed.
Claims10
A switch body comprising:
- a base including a first fixed electrode, a second fixed electrode placed next to the first fixed electrode to be electrically independent from the first fixed electrode, a third fixed electrode placed next to the second fixed electrode and on an opposite side of the second fixed electrode from the first fixed electrode, and a fourth fixed electrode placed next to the first fixed electrode and on an opposite side of the first fixed electrode from the second fixed electrode;
- and
- a movable electrode including a pressure receiving part opposite from the second fixed electrode of the base, a first outer edge facing the first fixed electrode, and a second outer edge facing the third fixed electrode, and being designed to allow movement of an opposite surface from the pressure receiving part toward the second fixed electrode when the pressure receiving part is pressed toward the base and then deformed,
- the fourth fixed electrode being formed in a region outside a projection region being a projection of the movable electrode on the base and being in a position facing the first outer edge of the movable electrode when the second outer edge of the movable electrode is moved to a region where the second fixed electrode is formed.
