Abstract

125,215. Read, A. E., Franks, J. E., and Brooks, M., (trading as Walsall Hardware Manufacturing Co.), and Compson, W. April 11, 1918. Plug couplings combined w i t h electric switches. A combined electric switch and plug- and-socket coupling contained within a casing is provided with throwing- off mechanism, which prevents the switch contact arm from remaining in its ' on' position except when the plug has been pushed home in the socket, so that the long or earthing pin of the plug engages with the throwing-off mechanism to move it clear of the path of the contact arm. The throwing-off mechanism comprises a tension spring 23, a lever 9, 14 with cranked end 10 and insulating-block 11, a link 15, and a lever 16. The spring tends to hold the block 11 over the end 13 of the switch arm 13<x>. When the plug has been inserted, the end 9 of the lever 9, 14 is raised and the block 11 is moved to a position clear of the path of the switch arm so that the switch can be closed by turning the shaft 3<x>. If, however, the plug be withdrawn before the switch has been opened, the long pin 20 of the plug moves clear of the throwing-off mechanism and the spring 23 then brings down the block 11 to engage with the arm 13<x> and open the switch.
