Abstract
In a first aspect of the present disclosure, a push switch includes a resilient member that is made of metal, and the resilient member including a concave shape and an opening that is positioned at a center of the concave shape and at least two protrusions each protruding outward and downward with an oblique angle around the concave shape.
Claims11
A push switch comprising:
- a resilient member being made of metal, the resilient member comprising:
- a concave shape being recessed downward in a plan view, and having a bowl shape and a curved surface;
- an opening being positioned at a center of a bottom of the concave shape;
- and
- at least two protrusions each protruding outward and downward with an oblique angle around the concave shape;
- a light-emitting element being arranged in the opening that is positioned at the center of the bottom of the concave shape of the resilient member, the curved surface of the concave shape of the resilient member surrounding the light-emitting element, and being configured to reflect light emitted from the light emitting element upward;
- an electrically-insulating member comprising upper electrodes being arranged on an upper surface of the electrically-insulating member, wherein
- the upper electrodes comprise at least one first electrode and at least one second electrode, the at least one second electrode being positioned outside of the at least one first electrode, and
- the center of the bottom of the concave shape of the resilient member is in constant contact with the at least one first electrode, at least one of the at least two protrusions being arranged above the at least one second electrode;
- and
- a film comprising a light-transmitting resin, the film being arranged over the resilient member,
- wherein the at least one of the at least two protrusions coming into electric contact with the at least one second electrode when the film is pressed down from above.
