ABSTRACT:
An electrical contact (100) for a lamp (10) that includes electrical lead-ins (20) projecting away from a longitudinal lamp axis (40), said electrical contact (100) has a first electrically conductive segment (110) including a first segment (120) leading to a first reentrant portion (130), a first beam (140) that extends from the first reentrant portion (130) to an electrical lead-in engager (150), and a second reentrant portion (160) that connects to a second beam (170) that at least partially extends over the electrical lead-in engager (150). A back-up spring (220) is provided having a configuration substantially conforming to the conductive segment (110). The back-up spring has a spring first segment (240) that leads to a first spring reentrant portion (250), thereafter to a first spring beam (260) that extends from the first spring reentrant portion (250) to a junction (261) at a region adjacent the electrical lead-in engager (150), the junction (261) connecting, in turn, the first spring beam (260) to a second spring reentrant portion (270), the second spring reentrant portion (270) connecting to a second spring beam (280) that abuts the second beam (170) of the conductive segment (110). The electrical contact (100) is preferably employed in combination with a socket (101) for receiving a lamp (10), the socket (101) formed of a first socket body portion (141) and a second socket body portion (147), with the electrical contact (100) being disposed between the first and second body portions.
