Changeable resistor with switch

Abstract

Provided is a variable resistor with a switch, which has a vibrating sound protrusion that contacts and separates from engaging portions (17c, 17d) of a vibrating sound member that rotates with the rotation of a rotating shaft (2) to generate a vibrating sound tactile sensation. parts (4d, 4e), the resistance substrate (5) forming the resistance body type plate (6) in sliding contact with the first sliding block (14), and the rotary switch that operates near the rotation end of the rotary shaft (2), the rotary switch It includes a contact substrate (10) forming a fixed contact (11), and a second sliding block (15) that rotates with the rotation of the rotating shaft (2). If the rotating shaft (2) is rotated, the second sliding block (15) When the switch is switched by sliding on the contact substrate (10), and the joint part (17c, 17d) of the vibrating sound member contacts and separates from the vibrating sound convex part (4d, 4e) to switch the switch vibrato touch. In this way, the thickness of the rotary shaft can be reduced in the axial direction, and a vibration-sound tactile feeling that does not feel strange when the switch is switched can be obtained.

Description

technical field [0001] The present invention relates to a structure of a variable resistor with a switch that can be miniaturized and provides a click feeling when rotating. Background technique [0002] As a conventional variable resistor with a switch, it is known that when the operating shaft is rotated by a predetermined amount from the initial position, the switch is switched from the closed state to the open state. When the operation shaft is rotated, the set resistance value changes (for example, refer to Patent Document 1). [0003] The structure of this existing variable resistor with switch is shown in Figure 29 ~ Figure 31 middle. Figure 29 is a cross-sectional view of an existing variable resistor with a switch, Figure 30 It is a plan view of the switch part incorporating the existing varistor with switch, Figure 31 It is an explanatory diagram of the operation of the vibrating sound (click) mechanism. [0004] In the schematic diagram, a conventional var...

Problems solved by technology

[0011] However, in a conventional variable resistor with a switch, since the structure of the switch unit 54 is complicated, there is a problem that the dimension in the axial direction of the operation shaft becomes long, and thus there is a problem that miniaturization cannot be achieved.
