Operating shaft is inserted into shroud and functions to transmit force to movable switching member through transmission gear. Each switching section has its transmission gear incorporating control disk mounted for displacement, positioned across shaft axis, and tightly joined with movable switching member. Transmission gear also has lever mounted on operating shaft. This lever is engageable with control disk and tightly coupled with the latter for definite positioning of control disk and movable switching member it carries along switching section axis in any angular position of operating shaft.
