Description

Push-button switch

Technical field

The utility model relates to a kind of contactor, relates to the push-button switch that a kind of installation dimension is φ 19 particularly.

Background technology

Domestic and international existing φ 19 push-button switches adopt plastic casing usually at present, its switch head is higher, intensity difference, yielding, the fracture, its hermetically-sealed construction generally has two kinds: 1) general waterproof jacket: sealing ring is enclosed within the button Head and Neck, the other end does not add fixing, make it slide up and down and swing when pressing the button head, though therefore sealing is arranged, still is easy to generate seepage.Its sealing property also is difficult to reach the requirement of regulation, and dust or moisture easily enter in the switch module from the slit between button and the housing, influence the useful life of push-button switch.2) senior waterproof (more than the IP65): be sealing shroud 5 to be enclosed within the button head outside whole head is closed, be used to press.It is neither attractive in appearance, and operation is also inconvenient, and sealing shroud 5 is easily aging or scratched by sharp device and lose sealing function, sees Fig. 1.In addition, switch protrusion switch panel 6 aspect ratios are higher, neither attractive in appearance when mounted for above-mentioned push-button switch, and also being collided with easily is damaged.

The utility model content

The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, intensity height, and the push-button switch of good seal performance.

For achieving the above object, the utility model adopts following technical scheme: a kind of push-button switch, comprise button assembly and switch module, described button assembly comprises button and the housing of button is installed, described button housing is made of metal, between described button and metal shell, be provided with elastic seal ring, this elastic seal ring top has the inward flange that inside ring-type is protruded, the bottom has the lower flange that protrudes to outer ring-like, in lower flange, be packaged with the embedded toroidal steel disc, described upper flange contacts with described button, and described lower flange contacts with the annular boss that is provided with in described metal shell.

Be provided with the ring edge that inwardly stretches out in described metal shell top edge, one ring set is set between described ring edge and annular boss, this ring set presses the lower flange of described elastic seal ring in annular boss, and being provided with annular groove at the external peripheral surface of described button, the upper flange of described elastic seal ring is embedded in this annular groove.This structural elasticity sealing ring not only can play sealing function, and its elasticity can also play the effect of push-button reset of allowing, and the ring set that is provided with and the annular groove of button also have the effect that limits button positions, promptly needn't add stopping means in addition, can prevent that also button from deviating from switch case or sink in the switch case.

Connect cross section, the coupling part shape linearly between described upper flange and the lower flange, form tubaeform elastic seal ring.

The cross section, coupling part that connects between described upper flange and the lower flange is the arc that is bent upwards, and forms the elastic seal ring with inside and outside ring wall, and its elasticity is better.

Be provided with luminescence component below described button, described luminescence component comprises LED lamp and the leg of drawing from the LED lamp downwards, and described ring set is made by light transmissive material and extend upwardly to button Face between button and housing, forms annular astigmatism body.

Be provided with luminescence component below described button, described luminescence component comprises LED lamp and the leg of drawing from the LED lamp downwards, at described button center drilling, inlays light transmissive material in the hole, forms the point-like astigmatism body.

Be coated with metal layer in the non-light transmission part of described button Face.

Owing between button and metal shell, be provided with elastic seal ring, elastic seal ring can play with button contacts with metal shell and lower flange has annular steel disc respectively by upper flange and lower flange lower flange is squeezed in the effect that metal shell prevents that elastic seal ring from going here and there up and down, can play better sealing function to push-button switch, prevent that dust or moisture from easily entering in the switch module from the slit between button and the housing, prolong the useful life of push-button switch; Switch case adopts metal shell and button Face covered with metal layer can increase the intensity of push-button switch, and under the requirement of satisfying intensity, can suitably reduce the thickness of switch case outboard flanges, thereby reduces the setting height(from bottom) of push-button switch.
