ABSTRACT:
An electric power supply operated switch clock comprises a housing with a synchronous motor in the housing which is adapted to drive a rotatable switch ring for timed rotary movement so as to cause riders positioned at selected one or ones of a plurality of switch rider receiving elements on the ring to engage and actuate a quick-break switchgear in the housing. The construction includes a plug head which is engaged on one end of the housing and a plug socket which is engaged on the other end with a pin bushing block being disposed therebetween. A synchronous motor mounted between the plug head and the plug socket is connected through a timing mechanism disposed around the pin bushing to drive the drive ring which is rotatable over a rib formed in a housing partition wall and on a socket cup which engages through the adjacent end wall. The construction includes a quick-break switch gear located in the housing around the pin bushing in a position to be engaged by one or more riders which are contained in the switch ring. The riders may be positioned adjustably around the circumference of the ring and located at a selected radial distance to engage one or more elements of a switch wheel to effect the desired timed switching.
