Multi-directional switching assembly which prevents rattling of drive members
Provided is an easily assembled multi-directional switching device that prevents the rattling of drive members, in which each pair of drive members mutually adjacent in the circumferential direction are connected to each other by an elastic arm member to form drive member units, and in which stem portions of the respective drive members are inserted in a casing from above corresponding guide holes to position the elastic arm members of the drive member units on the upper surface side of a top panel of the casing.
1. A multi-directional switching device comprising:
a plurality of switch units mounted on a printed circuit board;
a casing including the switch units therein;
a swiveling operation knob supported on a top panel of the casing;
four drive members interposed between the operation knob and the switch units;
the drive members being slidably inserted into a plurality of guide holes formed on the top panel of the casing, and the respective guide holes being arranged around the oscillation supporting point of the operation knob;
an arbitrary one of the drive members being connected via an elastic arm member to another one of the drive members located adjacent to at least one side of the arbitrary drive member in the circumferential direction, and the drive members being inserted in the casing from above the guide holes so as to position the elastic arm member on an upper surface side of the top panel of the casing;
two mutually adjacent drive members being connected with the opposite ends of the elastic arm member to form one drive member unit, and the four drive members being divided into two drive member units;
cylindrical members projecting from the top panel of the casing and being formed with the guide holes; and
skirt portions descending from an upper end surface of the drive members and overlapping outer walls of the cylindrical members.
