Abstract

A dial switch is provided with: a pivoting section (40) having an uneven peripheral surface (46a); a plunger (60); a holding section (52) for holding the plunger (60) so that the plunger (60) can reciprocate; and a coiled spring (51) for pressing the plunger (60). The holding section (52) has a guide surface (53) extending in the direction in which the plunger (60) moves and surrounding the plunger (60) from the outside. The plunger (60) is provided with: an outer wall section (63) which has an outer peripheral surface (63a) located close to the guide surface (53), and also has an inner peripheral surface (63b) having an inner diameter greater than the outer diameter of the coiled spring (51); and an inner shaft (64) which is located inside the outer wall section (63) and has a rear end located further toward the front side than the rear end of the outer wall section (63), the inner shaft (64) being adapted to enable the coil spring (51) to be mounted on the outer side thereof. The difference between the outer diameter of the inner shaft (64) and the inner diameter of the coiled spring (51) is less than the difference between the inner diameter of the outer wall section (63) and the outer diameter of the coiled spring (51).

Description

technical field [0001] The present invention relates to a dial switch for operating electronic equipment or the like mounted on a vehicle or the like. Background technique [0002] Conventionally, a switch disclosed in Patent Document 1 as a dial switch is known, which gives a user a feeling of a click sound when the user rotates a dial knob to operate an electronic device or the like. [0003] Such as Figure 8 and Figure 9 As shown, the dial switch includes an annular dial knob 102 and a support member (not shown in the drawings) that rotatably supports the dial knob 102 . The support member is provided with a detent portion 104 that gives the user a click sensation when the user rotates the dial knob 102 . [0004] The dial knob 102 has an uneven peripheral surface 106 on which radially indented recesses and radially protruding protrusions repeat alternately in the circumferential direction. The latch portion 104 includes a plunger 108 formed of a metal ball, a plunge...
