Canada: PART OF A LARGE COLLECTION OF ELECTRICAL ITEMS ACQUIRED BY ONTARIO HYDRO IN THE 1960S. THIS COLLECTION CONSISTS OF OVER 7500 ARTIFACTS, AND IS THOUGHT TO BE THE LARGEST & MOST COMPREHENSIVE IN CANADA. IT WAS DONATED IN ITS ENTIRETY TO THE NATIONAL MUSEUM OF SCIENCE &TECHNOLOGY IN 1992.
Function: USED TO CONNECT INCOMPATIBLE PLUGS AND RECEPTACLES.
Technical: THE TWIST LOCK DEVICE WAS A KIND OF SWITCHED RECEPTACLE. WHEN THE CAP WAS INSERTED AND TWISTED POWER WAS BROUGHT TO THE MOTOR AND WOULD LAST UNTIL THE CAP WAS UNLOCKED. USED FOR ELECTRIC MACHINES AND APPLIANCES. CONNECTOR BODIES WERE USED TO INTERCHANGE CERTAIN TYPES OF NON-STANDARD PLUGS INTO SOCKETS THAT WOULD NOT ACCEPT THEM (ESPECIALLY WITH APPLIANCES). THIS WAS PARTICULARLY A PROBLEM BEFORE APPLIANCE MANUFACTURERS ISSUED STANDARDIZED PLUGS WITH THEIR PRODUCTS. (REF. 1)
Area Notes: Unknown
