Abstract

The present invention relates to a reset button apparatus of a switch, mainly composed of a button, an outer casing and a button core, wherein the outer casing is step shaped and movably connected with the button, and the button vertically drives the button core to rotate around the axis of the button core. The reset button apparatus is characterized in that a reset spring is arranged between the inner portion of the button and the top of the button core; the top end of the inner portion of the button is provided with a groove, and the upper end of the reset spring is fastened in the groove; and the top of the button core is added with a boss, and the lower end of the reset spring is sleeved at the periphery of the boss. The structure design ensures that the button returns to an original position after the switch changes from the conduction state to disconnection state; the appearance is beautiful, and the visual sense is comfortable; the phenomenon that the switch is in conduction state all the time, since the button loses rebound performance after long term use, is avoided; and the service life of the button is also extended.

Description

A kind of switch reset button device

Technical field

The present invention relates to a kind of shift knob, especially relate to a kind of button can return to initial position after external force finishes switch reset button device.

Background technology

On the electrical equipment market, switch is the most common a kind of common electric elements, the effect of switch is used for control apparatus equipment break-make, the push-button switch key of regular tap as shown in Figure 4, mainly comprise button 1, shell 2 and button core 3, button 1 moves up and down and drives the axle center rotation of button core 3 along the button core, makes the moving contact contact fixed contact in the switch like this, makes circuit turn-on; Fig. 5, Fig. 6 are that switch is by the demonstration that is disconnected to conducting, button 1 can't be returned to original state among Fig. 6 behind switch conduction, like this, after switch was through use repeatedly, button 1 can lose ballistic properties, thereby made switch be in conducting state always, influence the action effect of switch, simultaneously, visually give the uncomfortable sensation of people, also influence its aesthetic property.

Summary of the invention

Technical problem to be solved by this invention provides a kind of increase the service life, guarantee visual effect and switch reset button device attractive in appearance.

The present invention solves the technical scheme that its technical problem takes: a kind of switch reset button device, mainly comprise button, shell and button core, shell is stepped, flexibly connect button on the shell, button moves up and down and drives the axle center rotation of button core along the button core, between described button inside and button core top one back-moving spring is set.

In order to guarantee that back-moving spring can also guarantee its bounce-back bearing of trend after long-term the use, the top of described button inside offers groove, and the back-moving spring upper end is fastened in the groove, and groove is cross inner groovy; The top of described button core adds a projection, and the back-moving spring lower end is enclosed within the projection periphery.

The invention has the beneficial effects as follows: this structural design guarantees that switch is by after being disconnected to conducting, can make button be returned to original position, guarantee its good looking appearance and euphorosia, simultaneously, avoided because long-term use of button loses ballistic properties, thereby make switch be in the generation of conducting state always, also prolonged the useful life of shift knob.

Fig. 6 is that original switching device is in the conducting state schematic diagram.

Among the figure: 1, button 1-1, groove 2, shell 3, button core 3-1, projection 4, back-moving spring.

Embodiment

A kind of switch reset button device shown in Figure 1, mainly comprise button 1, shell 2 and button core 3, shell 2 is stepped, flexibly connect button 1 on the shell 2, button 1 moves up and down and drives the axle center rotation of button core 3 along the button core, between described button 1 inside and button core 3 tops one back-moving spring 4 is set, and the top of described button 1 inside offers groove 1-1, back-moving spring 4 upper ends are fastened in the groove 1-1, and groove 1-1 is cross inner groovy; The top of described button core 3 adds a projection 3-1, and back-moving spring 4 lower ends are enclosed within projection 3-1 periphery, and groove 1-1 and projection 3-1 have fixed the bounce-back bearing of trend of back-moving spring 4.

Fig. 2, switch shown in Figure 3 are by being disconnected to conducting, shift knob 1 is pressed, 3 rotations of button core descend switch connection power supply, release button 1, button core 3 is locked by shell 2, switch continue to be connected, and button 1 resets to original position under back-moving spring 4 effects, guarantees that its outward appearance is not out of shape, bring visual effect to the client, guarantee its aesthetic property; Press the button 1 once more when needing deenergization, 3 rotations of button core descend, and button core 3 is discharged by shell 2, and power supply disconnects, and button core 3 and button 1 all reset, and finish make and break process one time.

This invention structural design guarantees that switch is by after being disconnected to conducting, can make button 1 be returned to original position, guarantee its good looking appearance and euphorosia, simultaneously, avoided because button 1 long-term the use loses ballistic properties, thereby make switch be in the generation of conducting state always, influence the action effect of its switch; Also prolonged the useful life of shift knob.
