Description

[Detailed explanation of the idea] The present invention relates to a four-way switch.

An object of the present invention is to provide a novel four-way switch in which switching operations of multiple circuits can be performed simultaneously by operating one operation knob in any of four directions.

Another object of the present invention is to provide a four-way switch which operates as described above and is simple in construction.

Yet another object of the present invention is to provide a four-way switch using opposed contact pieces.

The present invention will be specifically described below with reference to the illustrated embodiments.

A first embodiment is shown in FIGS. 1 and 2. In the four-way switch according to this embodiment, when the mover inside the switch case is moved in four directions by operating the operation knob, two adjacent opposing contact pieces disposed in each of the four directions inside the switch case are moved. This device is characterized in that it is capable of performing a switching operation of combinations of pairs.

The switch case is constructed by fitting an inner case 2 into an outer case 1 from below.

The outer case 1 has an inner wall 9,
The inner wall 9, the bottom wall 2f of the inner case 2, and the side wall 2
A square-shaped mover 3 is housed in a space 1c surrounded by g. The mover 3 is configured to be freely movable in four orthogonal directions by means of a lever 7. This lever 7 is connected to the upper wall 1 of the outer case 1.
It passes through a cross-shaped opening 1a formed in a and a spherical bearing part 9a formed in an inner wall 9. Lever 7 is
It has a spherical portion 8 in the middle thereof, and the spherical portion 8 is rotatably press-fitted into the spherical bearing portion 9 of the inner wall 9. Therefore, by operating the operation knob 6 formed at the upper end of the lever 7, the lever 7 can be moved along the cross opening 1a using the spherical bearing 9a as a fulcrum.
That is, it can rotate in four directions along the center line 0, 0'. The lower end of the lever 7 has a cylindrical portion 7a.
This cylindrical portion 7a is inserted into the central hole 3e of the mover 3. Therefore, as described above, when the lever 7 is rotated in four directions, the mover 3 is pushed by the cylindrical portion 7a and the inner case 2
It is adapted to move in the opposite direction to the knob 6 while slidingly contacting the bottom wall 2f of the knob 6.

The cavity 7b of the cylindrical portion 7a of the lever 7 houses a coil spring 4 and a protrusion 5 which is always urged downward by the spring. The lower end of this protrusion is pressed into a mortar-shaped recess 2e formed in the bottom wall 2f of the inner case 2, and when the lever 7 is rotated from the neutral position in either direction, the spring 4 is activated. The protrusion 5 resists the force and is guided by the inclined surface of the mortar-shaped recess 2e and rises inside the cavity 7b of the cylindrical part 7a, while when the hand is released from the knob 6 of the lever 7, the force of the spring 4 is increased. Then, the protrusion 5 is guided by the inclined wall of the mortar-shaped recess 2e and descends within the cavity 7b, and the lever 7 automatically returns to the neutral position.

In the space 1c of the switch case, there are four directions around the mover 3 (↑A', ↑B', ↑C', ↑D').
Opposed contact pieces A, B, C, and D are provided respectively. Each of the opposed contact pieces A to D is a fixed contact piece A ₁ , B ₁ , C ₁ , or D ₁ located on the outside and a spring movable contact piece A ₂ , B ₂ , C ₂ , D located on the inside. ₂ , and contact piece fixing protrusions 2a, 2b, 2c, 2 formed on the side wall 2g of the inner case 2, respectively.
It is fixed at d. As shown in the figure, each of the opposed contact pieces A to D extends horizontally and parallel to each side wall 2g of the inner case 2 or the front surface of each moving direction of the mover 3, and each of the opposed contact pieces Pieces A to D
The free ends of the two are also arranged in the same direction of rotation.

Each of the movable contact pieces A ₂ to D ₂ performs a switching operation relative to the fixed contact pieces A ₁ to _{D 1} as the mover 3 moves. There are pressing and sliding protrusions 3 on the front respectively.
a, 3b, 3c, and 3d, and each movable contact piece _A2 to _D2 has sliding contact protrusions 10a, 10b, 10c,
10d is provided. The above-mentioned pressing/sliding protrusion and sliding protrusion are 3a-10a and 3b-10.
b, 3c-10c, and 3d-10d, and therefore, when viewed counterclockwise in FIG. It is designed to be located close to the front. And each pressing/sliding protrusion 3a to 3d
The contact surfaces 3f for the sliding protrusions 10a to 10d that cooperate with each other are inclined, while the sliding protrusions 10a to 10d cooperate with each other.
0a to 10d are hemispherical.

In the above structure, for example, the mover is (↑A′)
When moving in the direction, the pressing/sliding protrusion 3a on the surface in the moving direction presses the movable contact piece _A2 to form a contact point a2 on the inside of the free end of the movable contact piece A2, and a contact point _a2 formed on the inside of the free end of the fixed contact piece _A2 . At the same time, the pressing/sliding protrusion 3d of the mover 3 contacts the movable contact.
By sliding against the sliding contact protrusion 10d of _D2 , the free end of the movable contact piece _D2 is urged outward, and its contact point _d2 contacts the contact point _d1 of the fixed contact piece D1 _. urge In other words, by rotating the knob 6 of the lever 7 in the direction (↑C') and moving the slider 3 in the direction (↑A'), the two opposing contact pieces A and D are simultaneously turned on. It is possible.

In the same way as above, mover 3 moves (↑B′), (↑
C') and (↑D') directions, the opposed contact pieces B and A, C and B, and D and C turn on simultaneously. In the figure, b ₁ , b ₂ , c ₁ , c ₂ , d ₁ , and d ₂ are contact points, respectively.

As described above, according to this embodiment, the pressing/sliding protrusions 3a to 3a correspond to the respective sliding protrusions 10a to 10d.
The relative positional relationship with 3d is constant for all four sets, and when the mover is moved in four directions, the four sets of combinations A-D, B of two adjacent opposing contact pieces
-A, C-B, and D-C switching operations can be performed.

In contrast to the above embodiment, another embodiment is shown in FIG. In this embodiment, the mover moves in four directions, but there are two combinations of simultaneous switching operations of adjacent opposing contact pieces (A and D: B and C).

That is, in this embodiment, compared to the first embodiment, the relative positional relationship between each pressing/sliding protrusion 3b, 3d of the mover 3 and each corresponding sliding protrusion 10b, 10d is the same. However, each press of the mover 3
The relative positions of the sliding projections 3a, 3c and the corresponding sliding contact projections 10a, 10c are reversed. Therefore, when the slider 3 is moved in the (↑A') direction or (↑D') direction, the opposed contact pieces A and D are turned on simultaneously in both cases, causing the slider 3 to move. When moving in the (↑B') direction or (↑C') direction, opposing contact pieces B and C are simultaneously turned on in either case.

Similarly to the first embodiment, this second embodiment also allows two adjacent opposing contact pieces to be simultaneously operated by moving the mover 3 in one direction, and is also similar to the first embodiment. Although it is not possible to make many combinations, the same two adjacent opposing contact pieces can be switched by moving the mover 3 in two different directions, which is very convenient depending on the application of the switch. .

In the above two embodiments, when the mover 3 moves in one direction, the facing contact piece in front of the direction and the facing contact piece on either side of the direction are turned on. However, it may be configured to turn off in that case.

As is clear from the above embodiments, the four-way switch according to the present invention can simultaneously switch two opposed contact pieces by one unidirectional operation, that is, can switch multiple circuits simultaneously. Not only is it extremely convenient to operate the slider, but it also has a simple structure in which a pressing/sliding protrusion is provided on the front surface of the slider in each direction of movement, and a sliding protrusion is provided on each movable contact piece. The functions and effects can be realized, and the intended purpose of the present invention can be achieved.
