Push switch

摘要

A push switch according to the present invention includes a case with a substantially-box shape, a cover, a manipulation member, a movable contact point, and a spring with a substantially-U-shape. The case with the substantially-box shape is provided with a common contact point and a fixed contact point in its inner bottom surface. The movable contact point is swayably placed on the common contact point and is extended in a leftward and rightward direction. The spring with the substantially-U-shape has one end hitched on a lower surface of the cover, the other end slidably placed on an upper surface of the movable contact point, and a center portion being in elastic contact with a lower surface of the manipulation member. This enables to make the entire push switch have a reduced height and to certainly connect and separate relatively-larger electric currents of about several amperes therethrough.

主权项

1. A push switch comprising:
a case with a substantially-box shape which has an inner bottom surface in which a common contact point and a fixed contact point are formed; a cover adapted to cover an upper surface of the case; a manipulation member which is housed in the case such that the manipulation member is movable in an upward and downward direction, the manipulation member having a manipulation portion protruded upwardly from the cover; a movable contact point which is swayably placed on the common contact point and is extended in a leftward and rightward direction orthogonal to the upward and downward direction; and a spring which has one end, another end and a center portion between the one end and the another end, the one end being hitched on a lower surface of the cover, the another end being configured to move slidably in the leftward and rightward direction on an upper surface of the movable contact point when the manipulation member moves in the upward and downward direction, the center portion being in elastic contact with a lower surface of the manipulation member, wherein a cross section of the spring linking the one end to the another end via the center portion has a substantially-U-shape.
