Description

Two slide switches

Technical field

The utility model relates to a kind of switch, is meant a kind of two slide switches especially.

Background technology

Be in and adopt in electrical equipment and the civilian use electric instrument etc. a kind of slide switch to control on/off and gear shift function usually, as high and low, close and change between the third gear, can satisfy the user ideally by slide switch and realize various own required functions.Announce " a kind of locking slide switch " (China, publication number CN200990324, open day 2007.12.12) as Chinese patent, comprise the housing of an electric upward insulation and be installed in the system of sliding of one in this housing restriceted envelope and make up.The combination of this slip system by stir the system button, promote the system button, promote the system button locking spring, positioning contact, keep in touch spring and the conduction slide is formed, wherein, locking screens on the promotion system button and the locking recess formation lock fit of locking spring assembly with the middle part that is located at the upper shell inboard.When the system of the stirring button of slide switch makes the system combination of sliding by dialing in the middle of two side direction when cutting out retaining, by promoting the locking spring of system button bottom, promote locking screens on the system button fall into the upper shell inboard the middle part the locking recess and the system combination of will sliding is automatically locked at the closed center retaining, thereby make this locking slide switch have on/off and gearshift function accurately.But, become flexible easily because its conductive feet (terminal supportor) is installed in the housing base plate; And the conduction slide slides on the conductive feet plane when sliding, and produces wearing and tearing; Therefore, influenced useful life.

The utility model content

The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of two slide switches are provided, and its contact is reliable, and long service life is applied to household electrical appliance and civilian use electric instrument etc., changes as gear (power).

For achieving the above object, the solution that the utility model is taked is: a kind of two slide switches, it comprises the base plate combination, sliding part combination and shell, both sides are shaped on respectively and are no less than three boss on the base plate, the boss outside is a socket, terminal supportor inserts socket, the plane of terminal supportor places on the boss, pressing plate and base plate snap together and compress terminal supportor, the plane of terminal supportor all exposes in pressing plate, in the middle of on the pressing plate is divider wall, divider wall is isolated the terminal supportor insulation on both sides, is shaped on the divider wall to be no less than two V-shaped grooves, base plate, terminal supportor and pressing plate constitute the base plate combination, mesopore is placed long spring and sliding pearl below the sliding knob, place two short springs respectively and snap in the slip springboard in the groove of both sides below the sliding knob, sliding knob, long spring, sliding pearl, short spring and slip springboard constitute the sliding part combination, and shell and base plate combination and sliding part combination fasten assembling, sliding pearl contacts with divider wall, and the slip springboard on both sides contacts with two terminal supportors on both sides on the base plate respectively below the cunning knob.

Operation principle of the present utility model is as follows: the slip springboard below the slider slip in the base plate combination, drive slider slides together, and the slip springboard contacts with two terminal supportors, reaches the energising function; Slider slides on divider wall and contacts with two different terminal supportors when being in diverse location, realizes gear (power) conversion.It is utilizer electrical appliance and civilian use electric instrument etc. widely.

Because the utility model adopts pressing plate and base plate to snap together and compresses terminal supportor, it is more smooth to make terminal supportor be difficult for plane loosening, terminal supportor, and not easy to wear during slip, has improved useful life widely.Divider wall in the middle of the pressing plate plays sliding pearl positioning action on the one hand, plays the effect of separating both sides electric arc, increasing creepage distance on the other hand.
