Description

[Detailed description of the invention] [Industrial field of application] The invention can be assembled so that the operating button can slide vertically or horizontally depending on the purpose of use. This is about an ultra-compact switch.

[Conventional technology]

As shown in FIG. 9, the conventional slide switch has leg pieces 25, 25 on the bottom plate 24 of the housing 30.
The contacts 26, 26 are press-fitted so that the contacts 26, 26 protrude downward, the clip 27 is slidably inserted between the contacts 26, 26, and the operating button 29 is pressed while the clip 27 is engaged with the slider 28. The contacts 26 and 26 were opened and closed by sliding in a straight line.

[Problem that the invention attempts to solve]

Ultra-compact switches, which are incorporated and connected to printed wiring boards in the same way as electronic circuit elements, are several mm to 10 mm in length, but in conventional slide switches, the slider 28 is as shown in Figure 9. Since the slider 28 is limited to linear sliding in the horizontal direction or the vertical direction (not shown), the slider 28 must occupy a minimum amount of space in which to move, and further miniaturization is not possible. In addition, in order to manufacture a switch whose actuating button moves in different directions, horizontal and vertical, each component must be manufactured separately, which is uneconomical.

[Means for solving problems]

The present invention was made to solve the above problems, and includes an insulating terminal board, a housing that fits into the insulating terminal board, a rotor rotatably mounted on the housing, A plurality of contacts provided on the insulating terminal plate facing the outer periphery of the rotor, a clip that slides on these contacts while engaging with the rotor, and a return spring that biases the rotor in one direction. and an actuation button that is freely disposed on the housing and rotates the rotor against the return spring.

[Operation] When the actuation button is pushed against the return spring, the rotor rotates, and the clip engaged with the rotor slides on the contact points to move toward and away from each other, thereby operating as a switch. At this time, the rotor does not require any space in the moving direction, so it can be made more compact.Also, by rotating the housing 180 degrees with respect to the center axis of the terminal plate and assembling it, the rotor can be assembled into two types: vertical sliding type and horizontal sliding type. Different types of switches can be made from the same parts.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 8.

Reference numeral 1 designates an insulating terminal board. This terminal board 1 is L-shaped with the same length and width (for example, about 5 mm), and is symmetrical about a 45-degree center line P, and its inner surface is aligned with the center line P. It is formed into an arcuate surface 2 with a point O on the line P as the center point. Two contact points 3, 3' are planted on both sides of the center line P along this circular arc surface 2, and these contact points 3, 3' are also formed in a circular arc shape, and furthermore, the leg pieces of the contacts 3, 3' are 4 and 4' pass through the inside of the terminal plate 1 and protrude from the lower surface. Housing locking protrusions 5, 5 are provided on both sides of the terminal plate 1 on the center line P. In this way, the terminal plate 1 is formed symmetrically with respect to the center line P except for the protruding positions of the leg pieces 4, 4', as shown in FIGS. 6 and 7.

A housing 6 is fitted into the terminal plate 1 at an angle of 45 degrees. The housing 6 has an open bottom surface and one side surface, and a through hole 9 for an actuation button 8 is formed in the top surface 7. The actuation button 8, which has a retaining edge 10 at the lower end, moves forward and backward from below the through hole 9. It can be inserted freely. A bearing hole 11 is formed in the center of both sides of the housing 6, into which a rotating shaft 14 of a rotor 12 is rotatably fitted, and engagement holes 13, 13 for engaging the terminal plate 1 are provided. This rotor 12 is approximately semicircular as shown in FIG. 4, and has a projection 15 at one end that is pressed by the operating button 8 to rotate the rotor 12, and a rotation shaft 1 at the other end.
One end 1 of a spiral spring 16 wound around 4
7 is engaged, and a holding groove 20 for holding the clip 19 is formed on the lower surface, and furthermore, on both sides of this holding groove 20, the contacts 3,
A slit 21 is provided so as to straddle 3'. As shown in FIG. 3, the spiral spring 16 has two spiral spring parts 16 ₁ on both sides of the one end 17.
16 ₂ , and the other ends 23 ₁ and 23 ₂ are engaged with a locking step 22 provided on the upper surface of the housing 6, and always urges the rotor 12 in the direction of pushing up the operating button 8. The clip 19 is fitted into the clamping groove 20 of the rotor 12 and slidably clamps the contacts 3, 3'.

In the above configuration, the operating button 8 is inserted into the through hole 9 of the housing 6 from below, and then the rotor 1 is engaged with the spiral spring 16 while the rotor 12 is engaged with the rotor 12.
The second rotating shaft 14 is press-fitted into the bearing hole 11, and the other ends 23 ₁ and 23 ₂ of the spiral spring 16 are locked to the locking stepped portion 22 of the housing 6. Further, the clip 19 is engaged with the holding groove 20 of the rotor 12.

When the housing 6 assembled in this manner is press-fitted into the terminal plate 1 from the direction of the center line P at 45 degrees, the housing locking protrusion 5 of the terminal plate 1 engages with the engagement hole 13, and the assembly is completed. During this assembly, as shown in FIG. 1, when the operating button 8 is located 180 degrees opposite the terminal leg pieces 4, 4', it is pressed from above. Also, as shown in Figure 8, the housing 6 should be
It is also possible to reverse the operation button 8 and assemble it so that it forms an angle of 90 degrees with the leg pieces 4, 4', in which case it can be pressed from the side.

The switch assembled in this manner pushes the protrusion 15 of the rotor 12 and rotates against the spiral spring 16 when the operating button 8 is pressed. This rotor 1
2, the clip 19 slides on the contacts 3 and 3' to short-circuit the contacts 3 and 3'. When the pressure on the operating button 8 is released, the clip 19 and the rotor 12 are rotated in the opposite direction by the spiral spring 16, and the operating button 8 is projected and returned to its original state.

The examples shown in Figs. 1 to 8 are examples of push-on type switches, but when the operating button 8 is not pressed, the clip 19 is tilted 45 degrees to short-circuit the two contacts 3 and 3', and the rotor is rotated. 12 and the short circuit between the contacts 3 and 3' is released when the operating button 8 is pressed, it can be made into a push-off type switch. Furthermore, the rotor 12 and the housing 6
It is also possible to provide a locking mechanism between the two, so that the lock is locked by the first push, and the lock is released by the second push. Moreover, not only one circuit of contacts made up of two contacts, but also two or more circuits of contacts can be made by arranging a large number of contacts.

[Effect of idea]

Since the present invention is constructed as described above, the sliding direction of the rotor and the clip is arcuate, and no extra space is required for the moving position of the rotor, making it possible to further reduce the size of the terminal board. The housing can be fitted by flipping it around the axis at an angle of 45 degrees, so even though they are exactly the same parts, by changing the way they are assembled, it can be used to make a push button switch in the vertical direction or a push button in the left and right direction. This has the advantage that it can also be used on a switch.
