A spring arrangement includes a cylinder member and a plunger member axially movable inward and outward of the cylinder cavity and resiliently biased outward of the cavity. The members conductively engage each other at rest and at least during a portion of the axial plunger member movement. They carry respective conductive terminals outside the cylinder cavity. The two spring members each may be hingedly connected to associated structures by means of a first connector, a first fastening device made of metallic material for fixedly fastening the element to the spring member, a second connector element secured to the first element for pivotal movement, and a second fastening device for fastening the second connector element to the associated structure. Insulation is interposed between the spring member and the associated structure for preventing flow of electric current in a path including the two elements and the two fastening devices. |
