Abstract
Differing from the conventional rotary switches, a rotary switch provided by the present invention is design to perform bidirectional rotation by double shaft, such that this rotary switch has the maximum switching levels of 32. Particularly, two retaining members having a spring accommodating trough are adopted for accommodating the compression springs; therefore, when switching the rotary switch from one switching level to another one switching level, each the retaining member does ensured to fully embed into one of the rotary grooves formed around the disk side edge of the corresponding rotary disks; the reason is that the compression springs suffer to pressing force would not bend during switching the novel rotary switch, such that the functions of the electric product can be switch smoothly and completely.
