Abstract
A rotary switch for an electrical appliance includes a housing adapted to receive a plurality of conductive wires, a plurality of conductive terminals fixedly mounted onto the housing, an actuation shaft rotatably mounted onto the housing, and a movable contact mounted onto the actuation shaft for selectively connecting two of the conductive terminals. The housing includes a base and a cover mounted onto the base. The cover includes a top surface, a bottom surface and a plurality of inwardly tapered guide walls. Each guide wall is shaped to define a slot into which an associated conductive wire can be securely retained in electrical isolation from the remainder of conductive wires. Each guide wall has a funnel-type configuration and includes a closed end and an open end, the slot being narrower at the closed end than at the open end.
