Abstract
A push switch includes a first fixed contact and a second fixed contact disposed apart from the first fixed contact. Furthermore, the push switch includes a dome-shaped metallic movable contact facing the first fixed contact with a space therebetween, and a protrusion disposed above a center of the movable contact. When the protrusion is pressed, the movable contact is elastically reversed, and the first fixed contact and the second fixed contact become electrically conductive with each other via the movable contact.
Claims6
A push switch comprising:
- a first fixed contact;
- a second fixed contact disposed apart from the first fixed contact;
- a movable contact facing the first fixed contact with a space therebetween, the movable contact being metallic and dome-shaped;
- and
- a protrusion disposed above a center of the movable contact,
- wherein when the protrusion is pressed, the movable contact elastically deforms, and while remaining deformed, the first fixed contact and the second fixed contact are electrically conductive with each other via the movable contact,
- wherein the protrusion is elastic,
- wherein a first force deforms the movable contact and a second force less than the first force maintains the movable contact deformed while the first contact and the second contact are electrically conductive with each other.
