    摘要: A time switch for automatically opening and closing switch contacts at pre-set times on consecutive days wherein an automatic cam is provided for automatically turning the switch ON and OFF at the same times on a number of consecutive days and a variable cam is provided for actuating the switch at preprogrammed different times on consecutive days. The AUTOMATIC cam is arranged for operating one pair of switch contacts while the VARIABLE cam is arranged for operating a second pair of switch contacts. A rotatable selector knob is provided with lugs for holding one or the other or both of said pairs of switch contacts in an open position to provide AUTOMATIC, VARIABLE, manual ON and manual OFF operation of the switch.
