ものとする。 1 to 8 are sectional views showing a switch according to an embodiment of the present invention, FIGS. 1 and 2 are a sectional side view and a sectional front view in an initial state, and FIGS. Cross-sectional side view and cross-sectional front view in the middle state, Figures 5 and 6
The figure shows a cross-sectional side view and a cross-sectional front view in the final state.
8 are a cross-sectional side view and a cross-sectional front view of a state in which the contacts are welded, and FIG. 9 is a cross-sectional view showing a conventional switch. In the figure, 2 is a support, 2b is a convex part of the support, 2c is a groove in the support, 3 is a movable contact, 6 is a push spring, 7 is a push rod, 7c is a projection of the push rod, and 7d is a push rod. 8 is a lever, 8a is a round bar part of the lever, 10 is a return spring, and 11 is a fixed contact. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims

[Claims for Utility Model Registration] (1) A movable contact support that is constantly biased downward by a compression spring and performs linear motion, and a movable contact support that is slidably supported by the movable contact support. with a contactor,
a spring that always urges the movable contact upward; a fixed contact whose contacts are opened and closed by the movement of the movable contact; and a rotatable lever that locks on the movable contact support; a return spring that constantly urges the movable contact support upward via the lever;
and a push rod that moves in a straight line by an external force, in the initial stage of operation of the push rod, only the push rod moves, and in the middle of the operation, the push rod rotates the lever to move the lever. A switch characterized in that the movable contact support is operated by the force of the push spring by releasing the lock between the movable contact support and the lever. (2) A utility model according to claim 1, characterized in that a part of the push rod is provided with a convex portion, and when the push rod is pushed down, the convex portion directly presses the movable contact support. switch.
