Abstract:
A contact comprising a torsion beam plate substantially lying in a plane, two side plates connected to two ends of the torsion beam plate, a curved spring arm extending from an edge section of the torsion beam plate and comprising an upper contacting section and a lower contacting section both of which are located at a same side with respect to the virtual plane, wherein the upper contacting section is located at the highest physical level of the contact and the lower contacting section is located at the lowest physical level of the contact, so that when the side plates are fixed in position and the upper contacting section and the lower contacting section of the curved spring arm are respectively engaged by two external contact pads sandwiching the contact, the torsion beam plate will be twisted for a predetermined angle to transmit reactive forces to the upper contacting section and the lower contacting section to abut against the contact pads, respectively;wherein each side plate has a narrower lower portion and curved wider upper portion;wherein the upper contacting section of the spring arm is distanced from the plane for a distance for generating a torque with respect to the torsion beam plate when the upper contacting section and the lower contacting section are engaged with the external contact pads;further comprising an end portion curvedly extending upward from the lower contacting section.
