Abstract
Abstract An electrical switch having vibration absorbing means to eliminate mechanical and electrical click noises raised therein during a switching action, which comprises an actuating member consisting of an inner member of elastic material supporting one or more movable contact members by direct contact therewith, and an outer member of rigid material securely supporting the inner member. The elastic inner member serves to absorb and restrain the vibrations of the movable contact members, occurring during the switching action.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
82 words
An electrical switch including at least one movable contact member of electrically conductive material; at least one stationary contact member of electrically conductive material cooperating with said movable contact member, and an actuating member bringing said movable contact member into and out of contact with said stationary contact member to perform a switching action; wherein said actuating member comprises an inner member of elastic material supporting said movable contact member and an outer member of rigid material securely supporting said inner member.
Claim 2
Dependent Claim
82 words
An electrical switch including at least one movable contact member of electrically conductive material; at least one stationary contact member of electrically conductive material cooperating with said movable contact member, and an actuating member bringing said movable contact member into and out of contact with said stationary contact member to perform a switching action; wherein said actuating member comprises an inner member of elastic material supporting said movable contact member and an outer member of rigid material securely supporting said inner member.
Claim 3
Dependent Claim
42 words
The switch according to claim 1 wherein the movable contact member is formed into an elongated leaf spring having its base end fixed, its intermediate portion supported by said actuating member and its free end adapted to contact said stationary contact member.
Claim 4
Dependent Claim
50 words
The switch according to claim 1 wherein said outer member has a looped portion securely encircling said inner member which has at least one aperture to allow the movable contact member to pass therethrough with both edges of said movable contact member pinched by the inner walls of the aperture.
