Abstract

A rotary switch with multi-level is disclosed. The rotary switch includes a rotary base that drives the first conductive sheet to rotate with the second conductive sheet when the rotary shaft is rotated, and the second conductive sheet leaves one of the conductive contact elements; the position end of the second conductive sheet is pressed by one positioning surface during the rotation, and the second spring stores energy; the second spring then releases the energy to the fourth end of the second conductive sheet, and the position end of the second conductive sheet slides on one positioning surface until the position end of the second conductive sheets is positioned solidly between two positioning surfaces; so that, the material cost in production can be lower down, and life time of the rotary switch can be increased.
