Abstract
Abstract A switch contact assembly is described which consists of a movable contact member having a resilient mounting member and a U-shaped resilient contact member held together at their free ends by insulation. The insulation reduces the capacitance between the contact member and the mounting member. Configuration of the contact member reduces the inductance of the contact member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
80 words
An electrical contact member for engagement and disengagement with a fixed contact member, comprising: a resilient mounting member for mounting the contact member on a mounting means and a free end; a resilient contact member having one end defining a U shaped contact member for reducing inductance of said contact member and a free end; and insulation means engaging both said free ends for insulatingly connecting said resilient mounting member and said resilient contact member and for reducing capacitance therebetween.
Claim 2
Dependent Claim
80 words
An electrical contact member for engagement and disengagement with a fixed contact member, comprising: a resilient mounting member for mounting the contact member on a mounting means and a free end; a resilient contact member having one end defining a U shaped contact member for reducing inductance of said contact member and a free end; and insulation means engaging both said free ends for insulatingly connecting said resilient mounting member and said resilient contact member and for reducing capacitance therebetween.
Claim 3
Dependent Claim
20 words
An electrical contact member according to claim 1 wherein said insulation means includes projectiOn means for engagement by actuation means.
Claim 4
Dependent Claim
17 words
An electrical contact member according to claim 1 wherein said U-shaped contact member defines dual contact sections.
