ABSTRACT:
A rotary electric switch having push-in wire terminals includes a hollow plastic housing having a recessed base and a cover, the base having a plurality of wire receiving openings. A plurality of resilient stationary contacts are positioned in the base, each resilient stationary contact being generally Z-shaped and having a locking tongue at one end, an intermediate arm, and a spring finger at the opposite end from the locking tongue. Each resilient stationary contact is positioned in the base with its locking tongue overlying a wire receiving opening in a side wall in the housing. A rotatable contactor is mounted in the base between the spring fingers of the resilient stationary contacts. A plurality of conductive plates are disposed in the base, one conductive plate associated with each resilient stationary contact, each conductive contacting the resilient stationary contact at a location its intermediate arm and in addition preventing a wire inserted into the opening from touching the sidewall of the housing. The housing includes a number of projections and standoffs to provide adequate spacing between current carrying components on the switch.
