Description

[Detailed explanation of the idea] [Technical field of invention] The present invention relates to an omnidirectional switch.

[Technical background of the invention and its problems]

Conventionally, commonly used switches are turned on and off by operating an operating body in one direction, as shown in, for example, Japanese Utility Model Application No. 58-52841.

Therefore, since the operating direction is determined, the mounting direction and position are limited when this is installed.

Furthermore, as shown in Japanese Utility Model Application Laid-Open No. 56-130238, there have been some devices in which the operation direction of the operating body is set to four directions, but the directionality is still determined, and there are restrictions on installation.

Further, as described in Japanese Utility Model Application Publication No. 52-162480, a cylindrical center terminal and an annular contact arranged concentrically with the center terminal are provided, and a dish-shaped contactor is provided at the center terminal. A structure is known in which the center of a movable contact is reversibly engaged, and a movable element is engaged with a shaft provided via a spring body to a shaft supporting an intermediate spherical part at the center of the movable contact. There is.

In this structure, the contact mechanism has a central terminal that is reversely displaced by the displacement movement of the shaft-supported mover in all directions. Shaped into a cylinder,
The contact element must also be annular, and the movable contact element must be formed into a dish shape, making the structure complicated, difficult to incorporate into a compact device, and resulting in large size and high cost. It is.

[Purpose of invention]

The present invention is an attempt to improve the above-mentioned points.The spring plate allows the operation body to move in all directions into a unidirectional movement, and uses a simple contact mechanism to make the operation body Operation direction is not limited,
The purpose of this invention is to provide a switch whose mounting direction, position, etc. can be freely set.

[Summary of the invention] The switch of the present invention has an operating protrusion protruding from the device body and the lower center of a circular push button via a fulcrum portion, and the device body has an operating protrusion projected from the central portion of the push button in all directions by the fulcrum portion. An operating body is supported such that it can be displaced by pressing the outer periphery of the push button, the base end is fixed to the instrument body, an actuator is attached to the lower part of the tip, and an operating protrusion of the operating body is attached to the top surface of the push button. a spring plate that forms a recess that engages in the horizontal state, and is actuated by being pushed by the operating projection by displacement of the operating body; a fixed terminal provided on the instrument body; and a spring plate that is fixed to the instrument body. A movable terminal is provided facing the terminal and has an actuator of the spring plate on its upper surface, and is moved toward and away from the fixed terminal by the operation of the spring plate. The operation of the operating body in all directions can be changed to unidirectional operation by the action of the plate, and the simple contact mechanism allows the movement of the fixed terminal and movable terminal by the action of the spring plate when the operating body is displaced in any direction. It is designed to allow conduction between the two.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes an instrument main body, and the instrument main body 1 includes a lower case 3 made of synthetic resin that is open on the upper surface and has a flange 2 formed on the outer periphery of the upper end, and a circular window hole 4 that is open on the lower surface and in the center of the upper surface. The upper cover 5 is connected to the lower case 3 by several screws 8 with a support 7 having a through hole 6 formed in the center thereof. .

A support body 10 having a spherical support portion 9 is attached to the upper center of the support 7, and an operating body 12 is supported on this support body 10. This operating body 12 has a spherical fulcrum portion 15 formed at the lower center of a circular plate-shaped push button 13 made of synthetic resin located within the window hole 4 of the upper cover 5 via a support rod 14.
An operating protrusion 16 is provided in a protruding manner at the lower part of the fulcrum portion 15 . The fulcrum portion 15 is rotatably fitted into the support portion 9 of the support body 10, and the push button 13 of the operating body 12 is rotated in all directions from the horizontal state.
It is supported so that it can be displaced by pressing the outer periphery of.

The base end of a spring plate 18 is fixed to the lower part of the support 7, and an actuator 19 made of an insulating material is attached to the lower tip of the spring plate 18. A recess 20 is formed into which twelve operating protrusions 16 engage and disengage. When the push button 13 of the operating body 12 is in a horizontal state, the operating protrusion 16 engages with the recess 20 of the spring plate 18, and the spring plate 18 is bent by being pushed by the operating protrusion 16 due to the displacement of the operating body 12. It is becoming more and more common.

A fixed terminal 22 having a fixed contact 21 is attached to the bottom wall of the lower case 3 with its terminal piece 23 protruding downward. Further, a movable terminal 25 having a movable contact 24 facing the fixed contact 21 of the fixed terminal 22 is mounted on the bottom wall of the lower case 3 with its terminal piece 26 protruding downward. Actuator 19 of the spring plate 18
are in contact with each other, and the movable terminal 25 is bent by the operation of the spring plate 18 to bring the movable terminal 24 into contact with and away from the fixed contact 21.

Then, from the off state shown in FIG. 1, that is, the state in which the push button 13 of the operating body 12 is in a horizontal state and the operating protrusion 16 is engaged with the recess 20 of the spring plate 18,
When an arbitrary point on the outer circumference of the push button 13 is pressed, the push button 13 rotates on the fulcrum 15 and the operating protrusion 16
is displaced to one side, the operating protrusion 16 is removed from the recess 20 of the spring plate 18, and slid on the upper surface of the spring plate 18, bending the spring plate 18 downward, and the movable terminal 25 is moved by the actuator 19. is pushed downward and tilted using one part of the movable terminal 25 as a fulcrum, and the movable contact 24 is brought into contact with the fixed contact 21 of the fixed terminal 22, so that the fixed terminal 22 and the movable terminal 25
conducts and turns on.

At this time, no matter which position on the outer periphery of the push button 13 is pressed, that is, no matter which direction the push button 13 is tilted, the spring plate 18 can be tilted correspondingly to turn it on.

Further, when the push button 13 is rotated from the on state to the horizontal state, the operation protrusion 16 engages with the recess 20 of the spring plate 18, and the movable terminal 2
5 is released, the movable terminal 25 returns upward due to its spring force, and enters the OFF state shown in FIG.

[Effect of idea]

According to the present invention, the contact mechanism has a simple structure consisting of a simple pair of fixed terminals that turn on and off by the action of contact and separation, and a movable terminal that connects and separates from the fixed terminals. Even if the operating body is displaced in any direction, the movement of the operating body in all directions can be made into a unidirectional movement by the action of the spring plate, and the fixed terminal and the movable terminal are electrically connected regardless of the displacement of the operating body in any direction. The contact mechanism has a simple configuration and can be obtained at low cost.Therefore, the operating direction of the operating body is not limited, and the mounting direction and position can be freely set. In the horizontal state of the push button, the operating protrusion engages with the recess of the spring plate and is positioned, so that the off state can be easily confirmed by the horizontal state of the push button.
