The present invention has a position restoring means (4) for restoring one end of the switch (3) to its original position when one end of the switch (3) is rotated with respect to the rotation shaft (2). In this embodiment, the position restoring means 4 is a spring for elastically pressing the other end of the switch 3 in a direction opposite to the rotational direction of the switch 3. Here, a compression coil spring is employed as the spring.

In this embodiment, a sensing unit 5 is provided for transmitting a signal to a controller (not shown) by interaction with the switch 3. The sensing unit 5 senses that the switch 3 is in contact with the rotation of the switch 3 and transmits the detected signal to the controller so that the controller can perform a specific operation, for example, on an image displayed on a monitor (not shown). do.

Hereinafter, the operation principle and operation of the computer mouse according to the first embodiment of the present invention will be described.

As shown in FIG. 3, when operation of the switch 3 is required while the bottom surface of the second case 1b is placed on the floor, as shown in FIG. 4, when the computer mouse is gripped and tilted to the left, the switch ( The other end of 3) comes into contact with the sensing unit 5 while pressing the spring 4 elastically. In this case, the sensing unit 5 transmits a signal to the control unit, which causes the object displayed on the computer monitor to perform a specific function.

In the state as shown in FIG. 4, when the computer mouse is restored to its original position as shown in FIG. 3, contact between the other end of the switch 3 and the sensing unit 5 is released by the restoring force of the spring 4.

Thus, the present invention has the advantage that the malfunction of the switch 3 can be remarkably eliminated by adopting a structure in which the switch 3 is not installed in the second case 1b placed on the floor. In addition, by adopting a structure to perform a switching function by the rotation operation of the switch 3, it is possible to replace the conventional switch 3 structure and has the advantage of operating the switch 3 precisely.
