Abstract
A multi-directional operating switch has a box-shaped case having an opening in an upper surface, a substrate disposed under the case, a tilting body having a manipulation shaft and disposed tiltably between the case and the substrate, and a plurality of switch units turned on and off by a depressing boss on a bottom fringe of a bowl-shaped section of the tilting body. An inner peripheral wall of the opening is provided with a plurality of recessed grooves elongated in an axial direction in positions corresponding with respective directions where the plurality of switch units are disposed, and an outer periphery of the manipulation shaft is provided with a plurality of protuberances for engagement with a corresponding one of the plurality of recessed grooves when the manipulation shaft is tilted. This structure allows for the multi-directional operating switch to have excellent operability, as any pushbutton switch other than a desired one is not turned into an ON state even if the manipulation shaft is tilted inadvertently in a direction deviated from the desired pushbutton switch.
