The invention discloses a sinking plate type miniature two-section side-push switch. The switch comprises an insulating base, a first conductive terminal, a second conductive terminal, a third conductive terminal, a first arched conductive clip, a second arched conductive clip, a metal cover and a first protective diaphragm, wherein the front edge of the bottom surface of the insulating base extends downward to form a sinking part, thus a longitudinally widened board can be formed on the front of the insulating base; each arched conductive clip can be perpendicular to a circuit board and longitudinally placed in a holding cavity of the widened board, which is different from the traditional structure that the conductive clip is parallel to the circuit board and placed crosswise; and the metal cover is provided with a push window, thus operations can be performed on each arched conductive clip directly and crosswise through the push window and a lateral button element is not required tobe arranged. Therefore, the product structure can be simpler, the product is convenient to produce and assemble; and the product has better hand feeling, contact performance, longer service life and higher market competition.
