Rotary universal switch

Abstract

The invention relates to a switch, and particularly relates to a rotary universal switch. The rotary universal switch is characterized by comprising an upper PCB (printed circuit board), a rotation controller and a lower PCB, wherein the front of the lower PCB is provided with multipath copper metal annular circuits and each path of control terminal, the structure of the back of the upper PCB is the same as that of the front of the PCB, the rotation controller is arranged between the upper PCB and the lower PCB, the rotation controller is provided with multipath contacts, the multipath copper metal annular circuits on the back of the upper PCB circuit board are communicated with the multipath copper metal annular circuits on the front of the lower PCB circuit boards through the corresponding contacts of the multichannel contacts. The switch provided by the invention is of a simple mechanical structure, namely, conductive circuits are directly arranged on the upper and lower PCBs, and the corresponding circuits on the upper and lower PCBs can be switched on / off through the multipath contacts arranged on the rotation controller, thus the multipath control can be realized.

Description

technical field [0001] The invention designs a switch, specifically a rotary universal switch. Background technique [0002] The universal transfer switch is a kind of manual electrical appliance with multiple operating positions and can switch multiple circuits. The existing universal transfer switch is generally composed of a cam mechanism, a contact system and a positioning device, and relies on the operating handle to drive the rotating shaft. And the cam rotates to make the contact act or reset, so as to connect or disconnect the circuit according to the required rules. At the same time, the positioning device ensures the accuracy and reliability of its action. Commonly used universal switches include LW5, LW6, LW8 and other series. These switches are all controlled by complex mechanical structures. After multiple actions, the coordination between the various parts will be misaligned, resulting in insensitive switches or inability to realize the on-off function. Conte...
