## Abstract

An electrical contact comprises a body portion defining first and second ends which are opposite to each other. A first spring arm extends from the first end, and a second spring arm extends from the second end wherein a displacement of a second contacting end of the second spring arm is orthogonal to a displacement of a first contacting end of the first spring arm. The second spring arm has a larger Young's modulus than the first spring arm.

## Claims

### Claim 1

An electrical contact for bridging a first device to a second device which is movably positioned respect to said first device, comprising:
a body portion for securely mounting to a supporting frame;
a first spring arm extending from an end of said body portion for selectively and electrically contacting said first device, said first spring arm forming a first contacting end; and
a second spring arm extending from the other end of said body portion for permanently and electrically contacting said second device, said second spring arm forming a second contacting end; wherein
when said second device is positioned at a first position, said first and second devices are electrically disconnected, and when said second device is positioned at a second position, said first and second devices are electrically connected;
wherein said first spring arm is directed such that the displacement of said first contacting end is in a first direction;
wherein said second spring arm is directed such that the displacement of said second contacting end is in a second direction which is orthogonal to the first direction;
wherein the Young's modulus of the first spring arm is smaller than the Young's modulus of the second spring arm;
wherein said second spring arm is convergent toward said second contacting end;
wherein said body portion includes an L-shaped configuration having long and short sides, said first spring arm extending from said long side, while said second spring arm extends from said short side;
wherein said second spring arm extends forwardly and upwardly from a bottom edge of said short side of said body portion.
