The thumb-acting switch body is a long rectangle framework, this thumb-acting switch body first half hollow depression one accommodation space, this thumb-acting switch body corresponds to the conduit of aforementioned upper cover plate, be embedded several pieces contact feets in the left side, and this contact feet protrudes out the thumb-acting switch body outside, be the staged turnover and be provided with; This thumb-acting switch body corresponds to the conduit of aforementioned upper cover plate, is embedded several pieces contact feets in the right side, and this contact feet protrudes out the thumb-acting switch body outside, is the staged turnover and is provided with;

Push button, apical margin central authorities are convexly equipped with a rectangle pushing block, and respectively establish a semicircular flanges in left and right two sides of apical margin; This push button is convexly equipped with four backstop pillars in root edge; Moreover this push button root edge connects the flexible contact flat spring of a metal material tool, these contact flat spring central authorities establish a circular hole in order to the snap flange that is convexly equipped with push button root edge central authorities mutually buckle connect;

In the ccontaining accommodation space that is arranged in thumb-acting switch body first half hollow depression of several push buttons, again upper cover plate is covered on thumb-acting switch body upper limb, the rectangle pushing block of push button apical margin central authorities is convexedly stretched in the conduit of upper cover plate, make its structure that is combined into one.

Owing to adopt technique scheme, can reach following beneficial effect:

(1) the utility model borrows left and right two sides of push button apical margin respectively to be convexly equipped with a semicircular flanges, fastens in the wavy backstop groove of the set semicircle of left and right two sides of upper cover plate root edge conduit, makes to stir the stable and accurate positioning of the action of switching push button.

(2) the utility model borrows push button to be convexly equipped with four backstop pillars in root edge, can prevent to use the improper deformation failure that causes contact flat spring of the application of force of operation, more increases accuracy and prolongation product useful life.

For concrete understanding structural feature of the present utility model and intension, describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
