In this case, as shown in figure 28, impact absorbing member 73 contacts with the facial 74A of erecting tools 74, button portion 5 is lifted because of the restoring force of movable electrode, respectively, there is gap T2 in the bottom of operating axis 67 and be arranged between the braking element 57 on the housing 1 and have gap T1 between the light guide plate 61 of button portion 5 and Lighting Division 4.

Secondly, the operation according to the push-button switch S of top described formation is described.

By being connected on the power supply, provide power supply to the built-in switch 2 that is connected on the tellite 55 via the connector 82 that lead 82a is connected on the tellite 55.

When the top 64 of the key by the knob down portion 5 that press...withes one's finger and during push axle 67, be arranged on the connection axial region 35 that bar contact site 69 on the operating axis 67 is pressed left and right sides rod component 34L, 34N.Thereby, left side rod component 34L is that the center rotates to counter clockwise direction in Figure 26 with its swing fulcrum P, and right rod component 34N is that the center rotates to clockwise direction in Figure 26 with its swing fulcrum P, as shown in figure 27, the rod bending point Q of left and right

sides rod component

34L, 34N is lifted.Thereby parallel moving done by button portion 5.

Like this, by lifting the rod bending point Q of left and right

sides rod component

34L, 34N, switch operating members 48 moves to the direction of pressing of button portion 5, and presses the button 30 of built-in switch 2 via noise reduction member 51.Thereby movable electrode is pressed and reverse rotation, and the travelling contact of this movable electrode contacts and become the state of switch connection with fixed contact.

In this case, the movable electrode of built-in switch 2 is pressed and reverse rotation, " click clatter " such noise that the travelling contact that utilizes noise reduction member 51 to eliminate this movable electrode sends when contacting with fixed contact.

Promptly, there be not noise reduction member 51, switch operating members 48 directly with situation that the button 30 of built-in switch 2 contacts under, when switch operating members 48 is directly pressed the button 30 of built-in switch 2, on the pressing force of this button 30, increased the pressing force of switch operating members 48 pressing buttons 30, the travelling contact of the movable electrode of built-in switch 2 increases to the impact velocity of fixed contact, and contact shock loading to each other increases, and makes a noise.

But, between the button 30 of switch operating members 48 and built-in switch 2, there is noise reduction member 51, thereby, when switch operating members 48 is pushed the button 30 of built-in switch 2 via noise reduction member 51, the spring force of noise reduction member 51 is to the directive effect opposite with the direction that presses the button 30, promptly, mode effect with the pressing force of offsetting switch operating members 48 pressing buttons 30, thereby, the travelling contact of the movable electrode of built-in switch 2 reduces to the impact velocity of fixed contact, this contact shock loading each other reduces, thereby abates the noise.
