Title:
可変抵抗器用スイッチ装置
Document Type and Number:
Japanese Patent JP6530870
Kind Code:
B2
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); switch terminals (120c, 120d); a cam (140a) that is arranged so as to be capable of rotating; a rotary member (130a) that, in response to the rotation of the cam (140a), switches the connection state between the 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 (139) that is provided on the rotary member (130a) and restricts the displacement of the spring member (150a) toward the substrate (100a). On either length-direction side of a portion thereof that contacts the restriction member (139) during the abovementioned restriction, the spring member (150a) has a portion that is not supported by other members.
