Abstract: There is provided a contact member for use in a lamp socket and particularly suitable for round terminal pins, the contact member and a recess for holding the contact member having a generally inverted V-shaped configuration, the contact member having a pair of opposed concave portions to receive the terminal pin of the lamp, the concave portions being flexible and biased so as to maintain good contact with the contact pin. The arrangement permits the miniaturization of the socket while also assuring excellent electrical contact between the contact member and the terminal pin ever after repeated usages.
