Title:
ROTARY SWITCH DEVICE
Document Type and Number:
Japanese Patent JP2017208201
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary switch device in which a producibility is increased by improving insertion operability of compression coil spring.SOLUTION: A rotary switch device comprises: a terminal base 3 to which a central part contact point 1 and a fixing contact point 2 are fixed; a rotational operation member 4 that can be rotatably operated around the central part contact point 1 to the terminal base 3; a plate-like movable contact point member 7 that includes a contact projection part 5 pressure-welded to the central part contact point 1 in one end of one surface of a plate-thickness surface, and a contact surface 6 with the fixing contact point 2 in other end, and that is held by the rotation operation member 4 and allows the central part contact point 1 and the fixing contact point 2 to be short-circuited at a conductive rotation position; and a compression coil spring 10 that is formed for energizing the contact projection part 5 and the contact surface 6 to the terminal base 3 side so that one end is supported by a bottom surface 9 of a spring housing hole 8 formed in the rotation operation member 4, and the other end is pressure-welded to a rear surface to the plate-thickness surface formed in the contact projection part 5 of the movable contact point member 7 and the contact surface 6.SELECTED DRAWING: Figure 8
