Abstract

A control stick includes a control portion, a first electrical contact portion and a second electrical contact portion. The control portion has plural first moving contact points, the first electrical contact portion has a control board and plural first static contact points corresponding to the first moving contact points respectively, and a gap exists between the first moving contact point and the respective first static contact point. The first static contact points are electrically connected with the control board. When the control portion swings towards one of the first moving contact points, the first moving contact point is contacted and conducted with the first static contact point. This control stick is capable of achieving the control of a multiple of variables to meet the requirements of controlling a multiple variable in some occasions.

First claim

What is claimed is:

1. A control stick, comprising: a control portion ( 1 ), a first electrical contact portion ( 2 ) and a second electrical contact portion ( 3 ), characterized in that the control portion ( 1 ) has a plurality of first moving contact points ( 11 ), and the first electrical contact portion ( 2 ) comprises a control board ( 21 ) and a plurality of first static contact points ( 22 ) corresponding to the first moving contact points ( 11 ) respectively, and a gap exists between the first moving contact point ( 11 ) and the respective first static contact point ( 22 ); the plurality of first static contact points ( 22 ) is electrically coupled to the control board ( 21 ), and when the control portion ( 1 ) swings in a direction towards one of the first moving contact points ( 11 , the first moving contact point ( 11 ) is contacted and conducted with the first static contact point ( 22 ); and the bottom of the control portion ( 1 ) is penetrated through the first electrical contact portion ( 2 ) and has a second moving contact point ( 12 ), and the second electrical contact portion ( 3 ) comprises a second static contact point ( 31 ) corresponding to the second moving contact point ( 12 ), and a gap exists between the second moving contact point ( 12 ) and the second static contact point ( 31 ), and when the control portion ( 1 ) is pressed, the second moving contact point ( 12 ) is contacted and conducted with the second static contact point ( 31 ).

2. The control stick as claimed in claim 1 , wherein the control portion ( 1 ) comprises an upper control module ( 13 ) and a lower control module ( 14 ), and the plurality of first moving contact points ( 11 ) is disposed at the upper control module ( 13 ), and the second moving contact point ( 12 ) is disposed at the lower control module ( 14 ); and when the upper control module ( 13 ) swings in a direction towards one of the first moving contact points ( 11 ), the first moving contact point ( 11 ) is contacted with the first static contact point ( 22 ); and when the upper control module ( 13 ) is pressed, the upper control module ( 13 ) presses at the lower control module ( 14 ), so that the second moving contact point ( 12 ) is contacted with the second static contact point ( 31 ).

3. The control stick as claimed in claim 2 , wherein the upper control module ( 13 ) comprises a knob control stick ( 131 ), a shaft ( 132 ), a housing ( 133 ), a ring-shaped elastic member ( 134 ) and a plurality of contact plates ( 135 ), and the first moving contact points ( 11 ) are disposed at the bottom of the contact plate ( 135 ) and a chute ( 1321 ) is disposed at the top of the shaft ( 132 ), and the knob control stick ( 131 ) is slidably coupled to an inner sidewall of the chute ( 1321 ); an arc portion ( 1322 ) is disposed at the bottom of the shaft ( 132 ), and the housing ( 133 ) has an arc chamber ( 1331 ) for receiving the arc portion ( 1322 ); and the arc portion ( 1322 ) has a cavity ( 1323 ) therein, and the chute ( 1321 ) is communicated with the cavity ( 1323 ), and an opening ( 1324 ) is formed at the bottom of the arc portion ( 1322 ) and provided for passing the knob control stick ( 131 ); when the knob control stick ( 131 ) is pressed, the knob control stick ( 131 ) passes through the opening ( 1324 ) presses at the lower control module ( 14 ); the housing ( 133 ) has a plurality of yield slots ( 1332 ) formed around the periphery of the arc chamber ( 1331 ), and the bottom of the contact plate ( 135 ) is pivotally coupled to the inner sidewall of the yield slot ( 1332 ); the top of the arc chamber ( 1331 ) has a ring-shaped slot ( 1333 ) extending outwardly, and the ring-shaped elastic member ( 134 ) is received into the ring-shaped slot ( 1333 ), and the ring-shaped elastic member ( 134 ) presses at the top of the contact plate ( 135 ).

4. The control stick as claimed in claim 3 , further comprising an elastic reset member ( 136 ) installed between the knob control stick ( 131 ) and the shaft ( 132 ).

5. The control stick as claimed in claim 3 , wherein the upper control module ( 13 ) further comprises a bottom casing ( 137 ) for placing the control board ( 21 ), and the housing ( 133 ) is covered onto the bottom casing ( 137 ).

6. The control stick as claimed in claim 3 , wherein the upper control module ( 13 ) further comprises a silicone cover ( 138 ), and the silicone cover ( 138 ) is covered onto the top of the housing ( 133 ), and the knob control stick ( 131 ) is penetrated through the silicone cover ( 138 ) and coupled to the silicone cover ( 138 ).

7. The control stick as claimed in claim 3 , further comprising an elastic overload member ( 139 ) installed between the first moving contact point ( 11 ) and the contact plate ( 135 ).

8. The control stick as claimed in claim 2 , wherein the lower control module ( 14 ) comprises a pressing structure ( 141 ) pressing at the moving touch plate ( 142 ) disposed at the bottom of the pressing structure ( 141 ) and provided for the pressing structure ( 141 ) to restore the elastic pressing member ( 143 ), and the second moving contact point ( 12 ) is disposed at the bottom of the moving touch plate ( 142 ), and the moving touch plate ( 142 ) is conducted with the second moving contact point ( 12 ).
