Knob switch device

A knob switch device, comprising:

• a knob portion comprising a knob configured to control an encoder;
• and
• a control circuit portion electrically connected to the encoder and at least one switching element,
• wherein the knob portion further comprises a trigger mechanism configured to trigger the switching element, and the knob drives the trigger mechanism to trigger the switching element by an axial movement,
• wherein the knob portion comprises a rotating shaft sleeve and a fixed shaft sleeve sleeved on outside of the rotating shaft sleeve, the knob is fixedly connected to the rotating shaft sleeve and movably connected to the fixed shaft sleeve, and the encoder is movably connected to one end of the rotating shaft sleeve,
• wherein the trigger mechanism comprises a first magnetic unit and a second magnetic unit in cooperation with each other, the first magnetic unit and the second magnetic unit are sleeved on outside of the fixed shaft sleeve, and the first magnetic unit and the second magnetic unit move along an axial direction of the fixed shaft sleeve;
• and wherein a magnetic pole of the first magnetic unit and a magnetic pole of the second magnetic unit are arranged in homopolarity, and the first magnetic unit and the second magnetic unit keep a distance due to a repulsive force between the first magnetic unit and the second magnetic unit.
