Title:
SWITCH DEVICE FOR VARIABLE RESISTOR
Document Type and Number:
WIPO Patent Application WO/2018/092224
Kind Code:
A1
Abstract:
The present invention restricts the displacement of a spring member toward a substrate and ensures the durability of a rotary member. The present invention comprises: a substrate (100a); a pair of switch terminals (120c, 120d) that are supported by the substrate (100a); a cam (140a) that is rotatably arranged upon the substrate (100a); a rotary member (130a) that is arranged upon the substrate (100a) and, in response to the rotation of the cam (140a), switches the connection state between the pair of switch terminals (120c, 120d); a spring member (150a) that is anchored at one end by the rotary member (130a) and at the other by the cam (140a) and, in response to the rotation of the cam (140a), makes the rotary member (130a) rotate; and a restriction member (109) that is provided on the substrate (100a) and restricts the displacement of the spring member (150a) toward the substrate (100a).
