ABSTRACT:
A resilient contact pin for contacting electrical or electronic items to be tested, such as conductor plates, printed circuit boards or the like, the resilient contact pin being electrically conductive and intended for mounting on a testing arrangement, includes a straight cylindrical member including a metallic tube constituted by a punched and bent sheetmetal part. A contact member includes a piston accommodated in the metallic tube for axial sliding and a frontward end portion projecting out of the metallic tube and serving for contacting the item to be tested. A spring is accommodated in the metallic tube and urged the contact member in a frontward direction relative to the metallic tube. There is further provided at least one lug constituted by an integral region of a circumferential wall of the metallic tube and extending into the interior of the metallic tube to constitute an abutment which limits the extent of the frontward movement of the piston of the contact member.
