Description

Switch with prevent button gap uneven structure

Technical Field

The utility model belongs to the technical field of the electronic switch technique and specifically relates to a switch with prevent button clearance inequality structure.

Background

At present, most of buttons of household wall switches (see seesaw switches as examples) are positioned by transition pieces in functional components, as shown in fig. 1, a pressing plate 7.2 is fixed on a fixing seat of a switch body, the transition pieces 7.3 are clamped and connected with the pressing plate 7.2, the buttons are clamped and connected with the transition pieces 7.3, the transition pieces 7.3 are driven by the buttons 7.1 to move to form seesaws, and on-off of the switches is achieved. However, the transition piece 7.3 is a moving part, the assembly of the transition piece 7.3 with the pressure plate 7.2 is a clearance fit, and the assembly of the button 7.1 with the transition piece 7.3 is also a clearance fit. Due to factors such as assembly clearance and accumulated errors, when one assembly relation fails, the transition piece 7.3 is easy to incline along the width direction of the button 7.1 (namely the X direction) in the process that the button 7.1 realizes the seesaw movement through the transition piece 7.3, the button 7.1 is also inclined, so that the clearance between two ends of the button 7.1 in the width direction and the panel is uneven, the friction between the button 7.1 and the panel is easy to occur, particularly in a multi-position switch, the button 7.1 is inclined, the clearances among a plurality of buttons 7.1 are uneven, the clearances among some buttons 7.1 are too large and are in a horn mouth shape (the clearances are gradually increased from the bottom to the top in the Y direction), and the appearance of a product is influenced; particularly, in the switch structure with a plurality of buttons, when the buttons are in a bell mouth shape (the gap gradually increases from the bottom to the top in the Y direction), at the smaller end of the bell mouth gap, when one button 7.1 is dialed, the button is easy to generate friction with the adjacent button 7.1, and abnormal sound is generated, so that the customer experience is influenced; some button 7.1 between the clearance undersize, zero clearance even leads to rubbing between the button 7.1 easily, can appear the phenomenon of linkage between the button 7.1 when serious, when the customer only need open a lamp, because the existence of this problem easily leads to a plurality of lamps to open simultaneously, seriously influences customer experience and uses at home.

In addition, the switch button in the prior art is controlled by four parts including the pressing plate, the transition piece, the button and the fixing frame due to the button gap, accumulated errors of the parts are excessive, the gap between the buttons is difficult to effectively meet design requirements, the phenomena of overlarge and undersize and deflection of the gap are extremely easy to occur, even serious scraping and button linkage phenomena are likely to occur, the quality is poor, and the use performance is influenced. Therefore, extremely high requirements are put on the die and the production process, the die cost is increased sharply, and the production and manufacturing difficulty is increased sharply.
