As described above, conventionally,
There was a separate switch for the push button operation and a switch for the lever operation, but there was no switch that could perform the push button operation and the lever operation with one switch. Therefore, when both the push button operation and the lever operation are to be performed, the switch by the push button operation and the switch by the lever operation have to be separately provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIGS. 1, 2, and 3 are a perspective view, a side view, and a plan view, respectively, of a switch 1 according to an embodiment of the present invention, and FIGS. 4, 5, and 6 are a longitudinal sectional view and an AA sectional view, respectively. It is a figure and a circuit diagram.

The switch 1 is a housing 1 made of an insulating material.
1 is provided with a hole 24 in the center thereof, and the shaft 6 is provided with a hole 25 provided on the lower end surface thereof so as to be rotatable and vertically movable by fitting into a column 13 planted on the bottom surface of the hole 24. The shaft 6 is fitted into the hole provided at the center to cover the upper surface of the housing 11. External electrodes 7-1 provided on the side surface of housing 11
0 is soldered to the circuit board 4. A pair of mutually insulated conductive contacts 14 and 15 are provided symmetrically around the center of the lower periphery of the shaft 6. The conductive contacts 14 and 15 are provided with convex portions facing outward, and a force for constantly pressing the convex portions against the inner surface of the hole 24 is applied by elasticity. A lateral groove 1 (in a direction along a plane perpendicular to the central axis of the shaft 6) is provided in almost half of the inner surface of the hole 24.
6 and 17 are provided, and electrodes 20 and 21 insulated from each other are provided along the upper and lower side surfaces of the upper lateral groove 16. The other portion of the inner side surface of the hole 24 has a vertical direction (axis 6).
Vertical grooves 18, 19 in a direction parallel to the central axis of
Electrodes 22 and 23 which are insulated from each other are provided along both side surfaces of the vertical groove 18. Electrode 20, external electrode 7, electrode 2
1 and the external electrode 8, the electrode 22 and the external electrode 9, and the electrode 23 and the external electrode 10 are connected by wiring (not shown).

As shown in FIG. 2 (a), when the lever 5 provided at the upper end of the shaft 6 is pulled up, the convex portion of the contact 14 is pushed into the lateral groove 16, and the electrodes 20 and 21 both contact the contact 14. , Between the electrodes 20 and 21, that is, between the external electrodes 7 and 8 form a closed circuit. When the lever 5 is pushed down as shown in FIG. 2B, the convex portion of the contact 14 is pushed into the lateral groove 17 and an open circuit is formed between the electrodes 20 and 21, ie, between the external electrodes 7 and 8.

[0011] The lever 5 as shown in FIG. 3 (a) from the top
When turned clockwise, the convex portion of the contact 15 is pushed into the vertical groove 18 so that the electrodes 22 and 23 are both in contact with the contact 15, and an open circuit is formed between the electrodes 22 and 23, that is, between the external electrodes 9 and 10. Become. As shown in FIG. 3B, when the lever 5 is turned counterclockwise as viewed from above , the convex portion of the contact 15 is pushed into the vertical groove 19, and the electrode 22,
23, that is, between the external electrodes 9 and 10 forms an open circuit. A pair of vertical ridge stoppers 26 provided at the boundary between the portion of the inner surface of the hole 24 where the horizontal grooves 16 and 17 are provided and the portion where the vertical grooves 18 and 19 are provided are connected to the contact 1.
The protrusions 4 and 15 are not allowed to pass over, and the contact 15 is prevented from entering the portion where the lateral grooves 16 and 17 are provided by turning the shaft 6 too much.

Therefore, the switch 1 constitutes the circuit shown in FIG. 6, and the opening and closing between the external electrodes 7 and 8 is performed by the vertical movement of the lever 5, and the opening and closing between the external electrodes 9 and 10 is performed by the rotation of the lever 5.

If a pair of electrodes which are insulated from each other are also provided in the lateral groove 17 along both side surfaces, a closed circuit is formed between the pair of electrodes when the lever 5 is pushed down, and an open circuit is formed when the lever 5 is pulled up. The lever 5 is opened and closed by inverting the lever 5 in a state opposite to each other between the pair of electrodes and between the electrodes 20 and 21.

Similarly, if a pair of electrodes insulated from each other are provided on both sides of the vertical groove 19, the space between the pair of electrodes and the electrode 2
The levers 2 and 23 are opened and closed by turning the lever 5 in the opposite state.

If three or more lateral grooves are provided instead of two, the opening and closing of three or more circuits can be switched by the vertical movement of the lever 5. However, only one of them is closed. Similarly, if three or more vertical grooves are provided, opening and closing of three or more circuits can be switched by turning the lever 5.

[0016]

As described above, the switch of the present invention can switch the opening and closing of one circuit by moving one lever up and down, and can switch the opening and closing of another circuit by turning it. Opening and closing of two or more circuits can be switched by operating one lever provided in the device, and a circuit that conventionally required two or more switches can be constituted by one switch, and the required space can be reduced. .
