Description

SUMMARY OF THE INVENTION [Technical Field] The present invention relates to a switch, σ, β _, and particularly to a rotary program switch. [Prior Art] As shown in Fig. 1 and Fig. 2, the rotary program switch 1〇 disclosed in Japanese Patent Laid-Open No. Hei 39997 has a base u, and a plurality of fixing legs 12 which are formed by the base η, are mounted. a movable contact block 13 of the base u, a fixing block 14 mounted above the movable contact block 13, a waterproof mat 15' mounted on the '11, rotatably mounted on the base " A knob 16 of the waterproof ring 15 and a top cover 17 disposed above the knob 16 and coupled to the base 11 are disposed. The knob 16 has a top surface (6) for arranging a cross recess for a turning tool (not shown), and a plurality of contact blocks 164 for separating the bottom surface 162 of the different contact pins 131 of the movable contact block 13. And an outer annular surface 163 which is connected to the top surface 161 and the bottom surface 162 and which is substantially wavy by a plurality of convex portions and concave portions. The top cover 17 has a top sheet 172 for providing a through hole 171 for exposing the top surface 161 of the crystal flip flop 6 from the opposite sides of the top sheet 172 to the bottom end for folding with the base U. The two coupling pieces 173 are bent from the other opposite sides of the top piece 172 toward the bottom end and are respectively provided with a convex portion 174 for pressing against the two abutting pieces i75 of the outer ring surface 163 of the knob 16. - By rotating the knob 16 pin 13 1 and the fixed connection of the rotary program switch 1 , although there is a function of enabling different contact blocks 164 to be pressed by different contact pins U, thereby generating different output signals. However, there are still the following disadvantages: b Since the S-shaped top cover 17 is biased by the convex portion 174 of the two abutting pieces 175 to the outer annular surface 163 of the red button 16, the knob 16 can only be applied horizontally. The force Fx cannot apply the vertical force of the knob 16, so that the contact quality of the contact pin 131 of the movable contact ghost 13 and the fixed contact pin 12 is affected, resulting in poor use quality of the rotary program switch 10. The top cover 17 is a horizontal 2 Fx ' that is applied to the knob 16 in a single direction and concentrated. Although the convex portions m can be used to firmly dust the surface 163 of the rotary knob, the relative cost is relatively large. The power to turn the knob 6 has the disadvantage of being labor-intensive. SUMMARY OF THE INVENTION SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a rotary program switch which can improve the quality of use and is less labor-intensive.

The tool (not shown) is combined with the base 20 to complete the assembly operation of the rotary program switch of the present invention, and the abutting portion 863 of the two tongue plates 80 presses against the oblique ring portion 715 of the knob 7A. As shown in Figures 3, 5, 6, 8, and 9, when the knob 70 is rotated, the contact blocks 74 can be rotated synchronously and the movable feet 45, 46 can be respectively pressed at different positions. , 47, 48, 49, such that the first activity contact foot 45, the second activity contact foot 46, the third activity contact foot 47, the fourth activity contact foot 48, the fifth activity contact foot 49 can The first fixed pin 3, the third fixed pin 33, the fourth fixed pin 34, and the fifth fixed pin 35 are in contact with each other, thereby generating different output nicknames. And in the process of rotating the knob 7 ,, when the groove 716 is aligned with the 5 abutting portion 863 a temple 'will be emptied by the abutting 胄 863, and the abutting portion 863 „ 亥 716 The v-shaped design 'and the abutment portion is slightly elastic by the thin metal plate t', so that the operator has a better operational feel. As shown in Figures 10, 11, 12, 13, the rotary program switch of the present invention A second preferred embodiment also includes a money 20, a fixed pin unit 30, a movable contact block 40, a fixed block 50, a waterproof ring 60, and a screw ring 7' 'And a top cover 80, 110, the fixed pin unit 30, the movable contact block 40, the = block 50 and the bribe (4) 6G design and the same - (four) = the same 'will not be repeated here. The knob 70 also includes a pressure ring, a plurality of contact blocks 74, a convex ring 75, a insertion tube 72, a sleeve and a slot 76, and a plurality of blocks 77. 'The pressure ring 71, with the first

The difference of the 旋 + a white 71 of the knob 70 of the embodiment is based on the connection of the pressure ring 71. Each face 713 has a flat ring portion 714' that surrounds the axis I with an equal diameter, - a ring portion 715' that is bundled from the flat ring portion 714' toward the axis J and connected to the bottom surface 711, and The plurality of V-shaped grooves 716 are disposed at the oblique ring portion 7]5 and are equiangularly distributed. The central angle Θ between the flat ring portion 714 of the connecting ring surface 713 and the oblique ring portion 715 is 15. To 7 〇. And the angle θ is 45. optimal. The top cover 8〇 also includes a through hole S1, a top plate Μ, and a combination of two

The plate 83 and the two wings 84 are respectively disposed on the two wings 84 and have a plurality of U-shaped grooves 85 and two tongue plates 86 formed by the two grooves 85, respectively. The top cover 8G' of the second preferred embodiment differs from the top cover 80 of the preferred embodiment in that each tongue is reversed 86 and has a connection to the flap. p 861', a bent portion bent from the connection 33861' to the shaft and the line I, and an abutting portion 863 which is placed on the bottom side of the bent portion 862 and punched toward the axis I. After the assembly of the rotary program switch of the second preferred embodiment of the present invention is completed, the abutment portion % of the five mystery tongue plate 86 can also be pressed against the knob 7〇, 12 1357610 715 and The same use effect of the first preferred embodiment. The technical features of the present invention and the efficiencies and advantages that can be obtained are as follows: the flat ring portions 714, 714 of the connecting toroids 713, 713, and the oblique ring portions 715, 715, The angle of absence is 0, and the angle Θ is 15 to 70. Thus, the abutting portions 863 and 863 are applied to the oblique ring portions 715 and 715 of the knobs 70 and 7'. Divided into a flat blade force Fx and a vertical component force Fy. In detail, the horizontal component force Fx is the horizontal thrust applied to the Yang 7G, 7()', so that the abutting portions 863, 863' can be firmly secured. The inclined ring portions 715, 715 are pressed, and the vertical component force is the downward pressure applied to the knobs 70, 70', and the downward pressure of the knobs 70, 70% to the A/3⁄4 movable contact blocks 4G can be increased. The contact effect of the movable feet 45 46, 47, 48, 49 with the fixed pins 31, 32, 33, 34, 35 can be improved, and the quality of use of the present invention can be improved. because. In the 863, 863' of the HM, the urging pressures of the spurs of the spurs 7 〇 and 7 〇 are naturally divided into a horizontal component force & and a vertical component force Fy. It is known that the top cover 17 of the rotary program switch 10 is unidirectional and concentrated horizontal force of the red button 16 , and the invention has the function of rotating the red 7G relatively effortlessly, so that the operation is more labor-saving, convenient and superior. The present invention is only a preferred embodiment of the present invention, and can be used to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the present invention in accordance with the present invention.
