Embodiment Construction
[0027] the following, Figure 1 to Figure 5 Embodiments of the present invention are shown. figure 1 It is an exploded perspective view showing the composite operation switch of the present invention; figure 2 It is a top view representing the compound operation switch of the present invention; image 3 yes figure 2 Sectional view of line 3-3; Figure 4 It is a sectional view of line 4-4 of 2; Figure 5 It is a top view showing the housing of the composite operation switch of the present invention.
[0028]In the figure, the housing 1 is formed of an insulating material such as synthetic resin into a box shape with an open top, and has a substantially circular storage portion 1a in the opening and a substantially square storage portion 1b connected to one end of the storage portion 1a. At the approximate center of the inner bottom surface of the substantially circular storage portion 1a, an annular support shaft portion 1c is formed protruding into the storage portion ...

A combined operation switch is provided. An operating member (6) is formed in a circular plain plate shape, having a projection (6a) for pressure on a central lower surface, the outer circumference surface of the operating member (6) is guided on the inner circumference surface of a spindle part (1c) so as to move in the vertical direction. The operating member (6) is arranged in a manner that it is energized upward by an elastic member (7), and an upper surface of the operating member (6) is exposed into a hollow section of a rotating body (8). Then, the operating member (6) is pressed by the pressure operation of the operating knob inserted in the hollow section of the rotating body (8), and a movable contact is made to be inverted by the projection (6a). The compound operation switch can accurately make a mutual contact of contacts, even when there is a displacement caused by end pushing, slanted pushing, etc. of an operating knob, when the operating knob for a pressure operation is large in size.
Description
technical field [0001] The present invention relates to a composite operation switch, and more particularly to a composite operation switch including a push operation switch and a rotary operation switch. Background technique [0002] As the structure of the conventional composite operation switch, it is known that a key switch for pressing operation and a switch for rotating operation are integrally built in a shared main body; and a rotor with brushes that slide with the switch plate. [0003] The structure of the conventional composite operation switch is as follows Figure 6 , Figure 7 shown. Figure 6 is a cross-sectional view of a conventional composite operation switch; Figure 7 It is a cross-sectional view of the key head and the key part of the reciprocating operation switch. [0004] In the figure, the composite operation switch has a main body 100 with a through hole 130 in the center, a substrate 200 with an opening corresponding to the through hole 130 in t...
