a channel through socket 10 in cross section lower chamber 28 is of a generally rotundate shape rear end 24 of socket 10 at upper chamber 26 is closed upper chamber 26 and lower chamber 28 are separated by thin wall 27 the details of which will be subsequently described contacts 16 are stamped and bent to their desired shape and are of a conventional tin plated copper electrical conducting material as previously explained because of the versatility of sockets 10 there is no 34 up 34 34 upward 34 34 down 34 or 34 downward 34 attitude however for purpose of illustration only we will herein consider lower chamber 28 to be on the 34 downside 34 and insulated wire 12 to be in a 34 downward 34 direction with respect to socket 10 as mentioned previously contact means 16 comprises a pair of mirror image conductors which connect the leads of wedge base lamps 14 to insulated wire 12 for purposes of simplicity in the explanation only one contact will be described the relationship of the two being clearly understood each contact 16 besst seen in fig3 and 4 is made of flexible spring like composition and comprises a generally rectangular base portion 32 of a size approximating the vertical 34 height 34 of chamber 26 bent from opposite surfaces and extending from base 32 are an upper arm 34 and lower arm 36 bent toward each other to receive and releasably.
