Abstract

The utility model discloses a button switch, in particular to a button switch with luminous display. A cover casing is provided with a base, a support frame, a cover board, a spring, a circuit board and a wiring terminal; the cover board is formed into an integral composite structure by the injection molding of thru hole type stainless steel panels and transparent plastic; a luminous body adopts light-emitting diodes for display, which are symmetrically combined. Compared with switches known by public, the utility model has the advantages of beautiful appearance, good brightness and clear font; the utility model can be on a par with foreign products.

Description

Button switch

The utility model relates to appliance switch, especially for the push-button switch in operation panel in the elevator sedan-chair and the Room door hall buttons.

The push-button switch that is used for elevator, because the needs of function must be in its surface sign direction of motion symbol or floor numeral, print or cover again but the cover plate structure in past adopts on carve characters japanning or the plastics with transparent plastic or polymethyl methacrylate, because frequent fingerprint, cause the font definition very poor, illumination effect is poor, influences good looking appearance.Along with the development of elevator industry, people are more and more higher to product design requirement handsome in appearance, and a high-caliber elevator must have the parts in addition of novel and beautiful next supporting, therefore, and the existing the sort of outmoded structure current people's of incompatibility psychological requirement.

Task of the present utility model is to design the push-button switch that a kind of novel structure is attractive in appearance, illumination effect is good and replaces prior art, the product of China can be compared favourably, from catching up with and surpass the international high standards with external product.

The utility model is achieved by the following scheme, by the push-button switch that case, base, support, spring, binding post, cover plate, wiring board etc. are formed, the stainless steel faceplate of the energy displaying symbol numeral of its cover plate employing open-work and the composite construction of transparent plastic integrated through injection molding; Luminous element adopts the light-emitting diode D of symmetrical assembled arrangement ₁-D ₁₂Show, constitute the push-button switch that the font symbol is clear, illumination effect is good.

This push-button switch is compared with known technology, good looking appearance, and illumination effect is good, and it has increased brilliance for complete machine, can compare favourably with external product.

Description of drawings.

Fig. 1 is the utility model structural representation.

Fig. 2 is № 1 a stainless steel faceplate structure chart.

Fig. 3 is the vertical view of Fig. 2.

Fig. 4 is the luminescent line structure principle chart.

Be described in further detail again by above-mentioned disclosed accompanying drawing embodiment.

Push-button switch (referring to Fig. 1-4) is that primary raw material is made with plastics, base (5) is equipped with in the interior bottom of case (8), support (4) is sleeved on the base can do upper and lower moving relative to base, spring (7) is made the usefulness that resets of support, the case top is provided with cover plate, both have the omoplate structure that matches, and play the position-limiting action of cover plate lifting.This cover plate is the composite construction by stainless steel faceplate of open-work (9) (1) and transparent plastic (2) integrated through injection molding, the patterning of open-work is decided on switching function, arrow or floor Digital ID or other symbol logo that can represent the direction of motion, Fig. 2 are the arrows that representative is risen.The making of cover plate is connected (seeing Fig. 2, Fig. 3) with thick 1 millimeter stainless steel faceplate (1) with screw (10) butt-joint earlier, then with transparent plastic (2) integrated through injection molding, the color of transparent plastic (2) just shows in open-work (9) through the effect of luminous element, does the special good indicative demonstration of emitting brightness to people.

Luminous element adopts the light-emitting diode D of symmetrical assembled arrangement ₁-D ₁₂Show resistance R ₁, R ₂Play the metering function (see figure 4).Its wiring board (3) is located at support (4) top, and the binding post that is connected with external power (6) interrelates with it, and binding post is fixedly mounted in the base.

The utility model need be made push-button switch on the product of luminous demonstration applicable to other.

Claims

1, a kind of push-button switch with luminous demonstration, base (5) is housed in the case (8), support (4) is sleeved on outside the base, spring (7) is arranged in the endoporus of support and base, the switch top is provided with cover plate, this cover plate and case (8) have the spacing omoplate that matches, and are fixed on the base with the binding post (6) that wiring board (3) links to each other with external power, it is characterized in that:

A. described cover plate is by the stainless steel faceplate (1) of open-work (9) and the composite construction of transparent plastic (2) integrated through injection molding;

B. luminous element adopts the light-emitting diode D of symmetrical assembled arrangement ₁-D ₁₂Show.

2, push-button switch as claimed in claim 1 is characterized in that described open-work (9) structure can be direction of motion arrow or floor Digital ID or other symbol logo.
