Claims

[Scope of Claim for Utility Model Registration] A switch knob, the switch knob being rotatably held on the upper surface,
a switch case having a plurality of pairs of cylindrical parts perpendicular to both sides of the rotation axis of the switch knob and a cylindrical spring holding part with an open top surface on the rotation axis; and a pair of cylindrical parts provided in the switch case. a pair of internal switches each mounted on a base plate fixed below the switch case at a position where the plunger comes into contact with a lower surface of each plunger; a feel protrusion made of resin, to which the switch knob is attached, and which has a feel groove formed of a plurality of notches in a number corresponding to the pair of cylindrical parts on its lower surface; and a spring holding part provided on the switch case. 1. A multi-step operation switch comprising: a spring housed in the spring; and a spherical body provided between the spring of the spring holding part and the tactile protrusion and biased by the spring.
