Technical field
The utility model relates to a kind of push-button switch, especially a kind of elevator button.
Background technology
Elevator button mainly is made up of the housing with peristome and the light-passing board, force transferring part and the circuit board assemblies that are contained in the housing, wherein circuit board assemblies is positioned at the housing inner bottom part, this circuit board assemblies comprises luminous component and the switch block that links to each other through conductor, light-passing board is contained in the housing of circuit board top slidably, be provided with force transferring part between light-passing board and circuit board, this force transferring part is relative with switch block.When the user pushed light-passing board, light-passing board moved down, and by force transferring part switch block was transmitted action force, make switch block conducting or disconnection, give elevator move instruction signal, simultaneously, control luminous component conducting or disconnection, show his mode of operation to the user.At present, force transferring part generally adopts plunger, and as Chinese patent 200520062980.4 disclosed a kind of illuminated push buttons, the upper end of plunger is step-like, is provided with boss with holes in the bottom surface of light-passing board, and insert in the hole of boss the upper end of plunger.Because light-passing board is at the thickness at the boss place thickness greater than other parts, and plunger also can stop the light that enters light-passing board, cause when luminous component is luminous, bad phenomenon such as stain or luminous dimness occur, influence display effect in the pairing light-passing board of plunger and light-passing board contact position position.
Summary of the invention
The purpose of this utility model is, a kind of stain, luminous uniform elevator button of can not occurring when luminous is provided, and improves the display effect of elevator button.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of elevator button, comprise housing and be located at this housing interior circuit board assemblies, force transferring part and light-transmitting component with peristome, wherein circuit board assemblies comprises luminous component and the switch block that links to each other through conductor, described light-transmitting component is arranged on close described peristome one side of this circuit board assemblies slippingly, between this light-transmitting component and described switch block, be provided with force transferring part, described light-transmitting component is the plane near the side of described force transferring part one side, the top that described force transferring part protrudes near oriented light-passing board one side of an end of this light-transmitting component.
Adopt this technical scheme, light-transmitting component thickness everywhere is even, has avoided when luminous component is luminous, bad phenomenon such as stain occur at the pairing light-passing board module position of force transferring part and light-passing board assembly contact position, has improved display effect.
The surface at described top is a cambered surface, adopts this structure, and force transferring part contacts for a face with light-transmitting component, and contact area is little, has avoided force transferring part to stop the light that enters the light-passing board assembly, and button is luminous more even, has further improved the display effect of button; And, because the surface at force transferring part top is a cambered surface, guaranteed when pushing light-passing board assembly surface any point, can correctly transmit power and touch switch parts, improved the performance of product greatly.
