Abstract

A seesaw switch, which is when it swings to make the contacting piece changeover between the contacting piece and the terminal piece related to the contacting piece, the wing press bar can complete the close and open operation of the related electrical circuit. The seesaw switch is characterized in that a roller is mounted at the contact place of the swing press bar with the contact piece. The structure is that the swing press bar rolls on the contacting piece to gain the switching operation of the contacting piece through the roller when it is swinging, It is the prior art which a sliding friction is changed into a rolling friction. The friction resistance ratio becomes much smaller. The swing press bar is therefore very flexible and smooth in the swing process, and has advantages of good handle feeling, little wear and long service life.

Description

A kind of rocker switch

Technical field

The utility model relates to a kind of appliance switch.

Background technology

Existing common hard and infertile switching plate as shown in Figure 3, other has Granted publication is that Fig. 7, Fig. 8 of the utility model patent specification of CN2458718Y also shows this structure, it is to drive the swing depression bar by the seesaw on the Push switch panel to swing up and down, contact chip is compressed or unclamp, and then the purpose that reaches out and close; Wherein swing depression bar and produce sliding friction in swing process and between the contact chip, exist bigger resistance, dumb when causing the switch seesaw to press, feel is poor, heatproof is low, the life-span is short.

The utility model content

The technical problem that the utility model also solves and the technical assignment of proposition be overcome that prior art exists resistance due to the sliding friction is big, dumb, feel is poor, heatproof is low because of the swing depression bar produces in swing process and between the contact chip, defectives such as the life-span is short provide a kind of new rocker switch.For this reason, the utility model adopts following technical scheme:

A kind of rocker switch is made between the lug plate of contact chip in correspondence in the swing on the contact chip by the swing depression bar and to switch the open and close that realize related circuit, it is characterized in that the contact site of described swing depression bar and contact chip is equipped with roller.

As the further of technique scheme improved and replenish, in the specific implementation, the utility model can also adopt following additional technical feature:

On described contact chip, its lower end offers blind hole to described swing depression bar by resiliency supported, inserts pellet shot from a slingshot in the blind hole as roller, does to close up and handle in the edge of blind hole.

The utility model is equipped with roller by the contact site at swing depression bar and contact chip, contrast with existing rocker switch, structure of the present utility model is when the swing of swing depression bar, by roller on contact chip scrolling realization to the switching of contact chip, thereby change the sliding friction of prior art into rolling friction, its resistance ratios is much smaller, thereby make the swing depression bar quite flexible, slick and sly when swing, good hand touch during use, it is little to wear and tear, and the life-span is long.

Description of drawings

Fig. 1 is an external structure schematic diagram of the present utility model.

Fig. 2 is that the A-A of Fig. 1 is to cutaway view.

Fig. 3 is the prior art constructions schematic diagram.

Among the figure: the 1-switch panel, the 2-seesaw, 3-compresses spring, and 4-swings depression bar, the miniature steel ball of 5-, 6-contact chip.

Embodiment

As shown in Figure 1, adorn a compression spring 3 in the upper end of swing depression bar 4, a small sircle hole is opened in the bottom of swing depression bar 4, adorns a miniature steel ball 5 in small sircle hole, to swing the depression bar bottom then and close up, miniature steel ball 5 can freely be rotated and can not come off in small sircle hole.

Drive seesaw 2 when pressing switch panel 1, swing depression bar 4 moves up and down under 3 effects of compression spring, miniature steel ball is rolled on contact chip 6, thereby contact chip is moved up and down as seesaw type, the effect of playing out and closing, because there is the existence of miniature steel ball 5 swing depression bar bottom, does rolling friction when switch is swung, seem quite slick and sly.

Claims

1, a kind of rocker switch is made between the lug plate of contact chip in correspondence in the swing on the contact chip by the swing depression bar and to switch the open and close that realize related circuit, it is characterized in that the contact site of described swing depression bar and contact chip is equipped with roller.

2, rocker switch according to claim 1, it is characterized in that described swing depression bar by resiliency supported on described contact chip, its lower end offers blind hole, inserts pellet shot from a slingshot in the blind hole as roller, do to close up and handle in the edge of blind hole.
