Mini Button Switch
Aug 31, 2018

The mini push button switch is integrally formed from a metal shaft, and the bottom is a guide piece. The shaft sleeve is sleeved with a spring and a lower gear to form a shaft center group, and the lower gear is blocked by the elastic force of the spring to the ring flange of the shaft center. The axial core group is disposed in the inner casing, the inner casing is disposed in the bottom casing, and the coil spring of the concave hole of the bottom casing abuts against the concave portion of the axial center, and the guide piece of the axial center and the terminal in the slot of the bottom casing maintain a certain distance In the open circuit, the upper gear passes through the copper head and is combined with the button. It has the advantages of quick and easy assembly, no falling off due to processing or operating vibration, greatly improving the withstand voltage, avoiding short-circuit faults, and preventing dust and moisture from entering the interior of the switch.

A mini push button switch is composed of a button, a copper head, an upper gear, an inner casing, a shaft center group, a bottom shell, two terminals and a coil spring, and the shaft group is sequentially arranged by an axis The set is composed of a spring and a lower gear. The upper gear is combined with the button through the copper head, the axial group is set from the bottom to the inner casing, the two terminals are set in the slot of the bottom case, and the bottom ends of the two terminals are downward. The bottom case is extended, and one end of the coil spring is disposed in the concave hole in the bottom surface of the inner wall of the bottom case, and the copper head is closed on the top end of the bottom case, and the upper and lower blocks of the upper and lower gears are respectively disposed at the upper and lower ends of the inner case groove. The upper and lower teeth of the upper and lower gears abut against each other, and the other end of the coil spring abuts against the concave portion at the bottom of the shaft center, and pushes the shaft center by the elastic force of the coil spring to guide the bottom of the shaft center. Forming a certain distance from the two terminals and maintaining the power-off state, wherein: the axial center and the guide piece are integrally formed by metal, and a ring flange is protruded outside the upper end of the shaft center, and a bottom end of the ring flange forms a stopping portion; The top surface of the lower gear is provided with a sleeve, and the inner diameter of the sleeve is slightly smaller than the outer diameter of the ring flange, the shaft Passing through the spring and the sleeve, and the sleeve is upwardly abutted against the stopping portion by the elastic force of the spring; an outer annular tip is formed on the outer side of the bottom end, and the inner receiving chamber is tightly fitted into the inner casing; the copper The bottom edge of the head extends downwardly and downwardly with a hook portion, the copper head cover is disposed on the top surface of the bottom shell, and the hook portion is embedded and riveted to the annular flange of the bottom shell.
