[0012] However, in the above-mentioned conventional multi-operation switch, when the operation knob inserted into the key head for pressing the key switch has a large shape, the operation knob is pressed from the end or obliquely pressed. , then the key head will be greatly inclined in the through hole of the main body, so that the protruding part arranged at the root of the key head will be disengaged from the snap metal plate of the key switch, resulting in the inability to contact the fixed tab. question

Embodiment Construction
[0029] 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.
[0030] In the figure, the housing 1 is formed of an insulating material such as synthetic resin into a box shape with an upper opening, and has an approximately circular storage portion 1a in the opening, and an approximately 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 storag...

A composite operation switch, the operation member (6) is formed in the shape of a circular flat plate with a pressing protrusion (6a) on the lower surface of the center, and the outer peripheral surface of the operation member (6) is guided by the inner peripheral surface of the fulcrum portion (1c) It can be lifted up and down, the operating part (6) is pressed upward by the elastic part (7), and the upper surface of the operating part (6) is exposed and arranged in the hollow part of the rotating body (8). In the pressing operation of the operating knob, the operating member (6) is pressed, and the pressing protrusion (6a) turns over the movable contact. In the case of such a compound operation switch, when the operation knob for pressing operation is relatively large, it can make accurate contact with each contact point even when the operation knob is biased such as end pressing or oblique pressing.
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 Image 6 , Figure 7 shown. Image 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 the...
