Abstract
A push switch includes a stationary contact and a movable contact. The stationary contact includes a base material and a conductive layer that covers the base material. The movable contact is disposed opposite a contact surface of the stationary contact. The movable contact is movable between a first position where the movable contact is in contact with the contact surface and a second position where the movable contact is apart from the contact surface. The stationary contact has a groove that divides the contact surface into a plurality of areas. Connection surfaces connect respective opening edges of the groove with a bottom of the groove. Each of the connection surfaces has a slope that is inclined at acute angle relative to the contact surface.
Claims18
A push switch comprising:
- a stationary contact that includes a base material and a conductive layer that covers the base material;
- and
- a movable component that has a movable contact on a surface of the movable component, the surface of the movable component being opposite the stationary contact, the movable contact being disposed opposite a contact surface of the stationary contact, the movable contact being movable between a first position where the movable contact is in contact with the contact surface and a second position where the movable contact is apart from the contact surface, wherein:
- the stationary contact has a groove that divides the contact surface into a plurality of areas,
- connection surfaces connect respective opening edges of the groove with a bottom of the groove, and each of the connection surfaces has a slope that is inclined at an acute angle relative to the contact surface, and
- a direction of rolling of the movable component intersects with a direction in which the groove extends, the direction of rolling being a direction in which a metal sheet, from which the movable component is formed, is rolled at a time of a manufacturing process of the metal sheet.
