Description of the invention $) and Figure 8 and Figure 9 show Another embodiment of the switch of the present invention is that the shaft 1 1 a of the button 11 is mounted on the housing 1 so that the button 11 can be rotated around the shaft 1 1 a and the button 1 1 Abutting on the movable contact point 7 and installing a spring 12 on the casing 1 is configured so that the button 11 is always pushed upward with one end of the spring 12 facing upward. The other structures are the same as those of the above-mentioned embodiment. Therefore, the same symbols are attached to the same parts, and descriptions thereof are omitted. As for this embodiment, when the button 11 is pressed in the direction of the arrow mark P in FIG. 9, the button 11 is opposed to the spring 12, and is rotated around the shaft 11a to be pressed into the housing 1. Since the contacts can be switched by the same operation as in the previous embodiment, the description thereof will be omitted here. [Effects of the Invention] In the open relationship of the present invention, the movable tangent point 7 is moved up and down by the convex portion 2 c of the housing 1 toward the axis of the pillar 2 b by moving the button 9 to form a sliding contact with the fixed contact 4, 5 With this structure, the oxide film of the contact portions 4a, 5a, 7a formed by the arc generated when the contacts are switched can be removed by the sliding action of the contacts, so that it can provide a switch that can be reliably contacted. Since the button 9 can be directly abutted on the movable contact 7, it does not require a known driving body, so it can provide a cheap and compact switch. The movable contact does not need to be manufactured as a conventional one, and it should be made of a metal plate with spring property. Therefore, an inexpensive switch can be provided.
