摘要: An assembly including a support plate carrying contact member on each face. A power cord terminal has an electrically-conductive pin projecting through aligned holes in the and members, ring surrounding insulated from it. spring cooperates with to press against one of members electrically connect other member. This invention relates electrical swivel which permits relative rotation between interconnected terminals while permitting flow electricity terminals. The will be described connection electrically-heated curling iron. However, it is understood that may used advantageously hand-held appliances, types electrically-powered apparatus. When iron used, rotated about its longitudinal axis order coil hair around causes supplying become twisted. As time goes on, twisted becomes both inconvenience danger. Therefore, been suggested past irons include assemblies permit without twisting cord. such have complex expensive, initial cost materials assembly. It is, therefore, object present provide very simple, inexpensive, easy assemble. another pair relatively moving contacts biased into engagement, being connected provides bias. further two are mounted single adapted fixed within housing appliance, these cooperable, respectively, coaxial elements presented by terminal. additional wherein rotatable respect carries, good maintained respectively. Additional objects features apparent following description, reference made accompanying drawings:
