The invention discloses a hidden type mining single switch, and relates to the technical field of electric power equipment. The hidden type mining single switch comprises a panel, a switch button and a circuit board cover board, wherein the circuit board cover board is arranged on one side of the middle part, where the switch button is movably arranged, of the panel; the hidden type mining single switch also comprises a back cover, screws, shafts, a limiting board, a hinge, and a return spring, wherein the back cover is fixedly connected with the panel through the screws; the shafts are arranged on the front and back sides of the back cover in a penetration manner; threading holes are formed in the front and back side walls of the back cover; the limiting board is rotationally connected with the bottom of the back cover through the hinge; the return spring is arranged between the limiting board and the back cover; the shaft consists of a shaft rod, a positioning board and positioning columns; the positioning board is arranged at one end of the shaft rod; the multiple positioning columns are arranged on the positioning board in a circumferential manner; and positioning holes which are matched and clamped with the corresponding positioning columns are arranged on the front and back side walls of the back cover. By adoption of the hidden type mining single switch, a condition that dust enters the interior of a switch key to influence the press-down of the switch key is avoided; abrasion caused by dust is reduced; and the hidden type mining single switch is high in practicability.
