Document Type and Number:
WIPO Patent Application WO/2011/064953
Kind Code:
A1
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).
