Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to a so-called alternate type switch device that is alternately switched between, for example, an on state and an off state.

(Prior Art) Conventionally, a seesaw type switch device is well known as this type of switch device. In this device, a switch element can be switched between an on state and an off state by alternately pressing both ends of a seesaw-shaped control element with a moderation mechanism. Once in the on state, the on state is maintained by the action of the moderation mechanism until the next pressing operation to turn the off state. The structure of this moderation mechanism is, for example, when the operator is in the on or off position, a steel ball provided on the operator side is urged by a spring into a groove provided on the switch body side and pressed into contact with it. ,
Thus, the operator is held in one of the above positions.

(Problem to be solved by the invention) However, in the case of the above-mentioned device, it is necessary to provide space within the switch body for the parts that make up the moderation mechanism, so it is difficult to downsize the entire switch device. There was a problem.

The present invention was devised in view of the above circumstances, and its purpose is to provide a switch device that can reduce the overall size by eliminating a complicated moderation mechanism.

[Structure of the device] (Means for solving the problem) The device of the present invention is capable of moving an operator that is displaced to a pressing position to actuate a switch element to the switch body in a pressing direction and in a lateral direction orthogonal to the pressing direction. In a switch device in which the operator is always urged in the opposite direction to the pressing operation by an elastic body while being prevented from coming off from the switch body, a sloped portion is provided on one of the switch body side and one end side of the operator. is provided, and a contact portion corresponding to the slope portion is provided on the other side, and a locking surface portion corresponding to the other end portion of the operator is provided on the switch body side, and the operator is tilted so that the contact portion corresponds to the slope portion. When the other end of the operator is pressed so that the slant surface and the slanted surface come into contact with each other, the other end of the operator is pressed against the locking surface by the elastic force of the elastic body and held at the pressed position. It is characterized by being configured as follows.

(Function) When the other end of the operator is pressed to tilt the operator, the operator tilts in a loosely fitted state with the switch body. Then, when the pressing operation is finished,
The contact portion contacts the slope portion and presses the other end of the operator against the locking surface portion. Then, the operating element is held in a pressed position in pressure contact with this locking surface portion, thereby maintaining the switch element in an activated state.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

First, in FIG. 1, reference numeral 1 denotes a box-shaped switch body, and a rectangular opening 2 is provided in the upper surface of the switch body. Reference numeral 3 denotes an operator, which has a rectangular plate-shaped operation part 3a with retaining parts 3b and 3c integrally protruding from one end (left end in the figure) and the other end (right end in the figure), respectively. , the operating portion 3a is positioned within the opening 2 of the switch body 1 so as to be movable vertically and laterally, and the retaining portion 3b,
3c prevents it from coming off from the switch body 1. Reference numeral 4 denotes a printed circuit board fixed to the lower surface of the switch body 1, and a pair of fixed contacts 5, 5 are provided at the center of the upper surface of the printed circuit board. This fixed contact 5 can be connected to an external circuit via a conductive pattern (not shown) on the printed circuit board 4. 6 is an elastic body made of rubber, for example, and includes a cylindrical main body 7, a skirt 8 extending obliquely downward from the outer periphery of the main body 7, and an annular base plate 9 connected to the skirt 8. It is integrally formed. This elastic body 6 is disposed on the printed circuit board 4, and in this state, the upper surface of the main body 7 comes into contact with the approximate center of the lower surface of the operator 3, and urges the operator 3 in the counter-pressing direction (upward). With this, the operating portion 3a of the operator 3 is supported at a protruding position protruding from the switch body 1. Further, on the lower surface of the main body 7 of the elastic body 6, a conductive film 11 that constitutes the switch element 10 is provided opposite to the fixed contact 5 of the printed circuit board 4, and when pressed by the operator 3, the lower surface of the main body 7 is When brought into contact with the printed circuit board 4, the switch element 1
0 is turned on.

On the other hand, a receiving step portion 12 is provided inside the left side wall portion of the switch body 1 in the figure to protrude inwardly, and the tip of the left retaining portion 3b of the operator 3 in the protruding position is attached to the receiving step. It is located on section 12. The retaining portion 3b located at the left end of the operator 3 corresponds to the abutting portion in the present invention, and the switch body 1 has a slope corresponding to the retaining portion 3b. A portion 13 is formed. This sloped portion 13 is formed on the left side wall of the switch body 1 so that the wall thickness becomes thicker toward the top, and its lowermost end is connected to the top corner of the retaining portion 3b of the operator 3 in the protruding position. They are in approximately the same position. Further, the right side wall portion 14 located on the right side in the figure of the switch body 1 corresponds to the locking surface portion according to the present invention, and when the operator 3 is in the protruding position, the right side wall portion 14 located on the right side of the switch body 1 corresponds to the locking surface portion according to the present invention. 3c are facing each other for a short time.

Next, the operation of the above configuration will be explained.

When turning on the switch element 10, first,
Press the right end of the operating section 3a, that is, the other end. Then, the operator 3 tilts in the direction of arrow A around the contact portion with the elastic body 6 in a loosely fitted state with the switch body 1, and the left retaining portion 3b comes into contact with the slope portion 13. When the operator 3 is pressed further, the operator 3 tilts further and moves the main body 7 of the elastic body 6 downward against the elastic force of the skirt 8, and finally, as shown in FIG. As shown in FIG. 3, the main body 7 is slightly compressed and moved to the pressing position where it comes into contact with the printed circuit board 4, and the switch element 10 is turned on. After reaching this pressing position, when you release your finger from the operator 3, the operator 3 is pushed back slightly upward by the elastic force of the elastic body 6.
As a result, the left retaining part 3b is strongly pressed against the slope part of the switch body 1, and the operator 3 is moved against the elastic body 6.
is pushed to the right by the elastic force of For this reason, the right side retaining portion 3c of the operator 3 is attached to the switch body 1.
is pressed against the right side wall 14 of the controller 3 due to frictional force.
is held in its pressed position to maintain the on state of the switch element 10.

To turn off the switch element 10 from this on state, the left end of the operator 3 is pressed downward to tilt the operator 3 in the opposite direction of arrow A from the pressed position. Then, the retaining portion 3b separates from the slope portion 13, so that the rightward pressing force applied to the operator 3 from the slope portion 13 disappears, and the state of pressure contact of the retaining portion 3c against the right side wall portion 14 is released, allowing operation. The child 3 is moved back to the off position shown in FIG. 1 by the elastic force of the elastic body 6. As a result, the main body 7 of the elastic body 6 separates from the printed circuit board 4, so that the switch element 10 is turned off.

Now, according to the above configuration, when the operator 3 is pressed, the operator 3 is tilted and held at the pressing position where the switch element 10 is turned on by the slope portion 13 and the right side wall portion 14. It is not necessary to use a complicated mechanism such as the conventional moderation mechanism, and therefore, the space for arranging the moderation mechanism can be omitted and the entire switch device can be miniaturized. Moreover, according to this embodiment in which the switch element 10 is configured by the conductive film 11 provided on the bottom surface of the main body part 7 of the elastic body 6 and the contact point 5 on the printed circuit board 4, the switch element 10 can be simplified and the switch It is possible to achieve miniaturization of the entire device.

In addition, the operator 3 is loosely fitted to the switch body 1 so that it can move in the pressing direction and in the lateral direction perpendicular to the pressing direction. Even if they tilt while contacting the switch body 1, the contact force between them is slight. Therefore, the operability of the operator 2 can be improved.

It should be noted that the present invention is not limited to the above-mentioned embodiment. For example, a sloped portion may be provided at one end of the operator 3,
A contact part may be provided on the inner surface of the switch body 1, and the contact part may press the slope part to press the other end of the operator against the locking surface part.
Various modifications can be made without departing from the gist of the invention.

[Effects of the invention] As is clear from the above description, the present invention is provided with a slope portion and a locking surface portion that tilt the operator and hold it in the pressed position when the operator is pressed. This provides an excellent effect in that the operator can be held at the pressed position without using a complicated mechanism, and the entire switch device can be made smaller.
