A Ground Fault Circuit Interrupter (GFCI) interrupts the flow of current through a pair of lines extending between a source of power and a load. The GFCI includes a circuit breaker, a relay circuit including a solenoid, a latch circuit, and a fault detecting circuit packaged in a circuit assembly. The GFCI is adaptable for a quick connect of a load input cord by a user, allowing for various configurations of cords to be utilized on site, the cord easily connected from the device being protected to the GFCI at the point of use. The GFCI circuit assembly includes a load input section having cable securement jaws for connection of the load input cable terminal ends.

An electric plug includes an end block and a power cord. The end block includes a plurality of first connectors and the power cord includes a plurality of second connectors which correspond to the first connectors and detachably connected thereto. The first connectors and second connectors are electrically conductive. One or more first connectors are connected to the second connectors by press-fitting and are retained therewith by friction. Alternatively, the first connectors may be a terminal screw assembly and the second connectors are wires of the power cord.

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.

Cover for a rotary switch

A housing for an electric switch includes a recessed base and a cover member. The cover member is constructed to include a hook fastener, a latch fastener, a first pair of clip fingers and a second pair of clip fingers. The hook fastener and latch fastener serve to enable the electric switch to be easily and quickly mounted on a wall in a device with which the electric switch is to be used while the first and second pair of clip fingers serve to hold the hook and latch fasteners tightly in place on the wall of the device when so mounted.

Housing for an electric switch

Miniature rotary electric switch

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.

A miniature rotary electric switch having push-in wire terminals comprises a housing which is about 1 inch in length, 1 inch in width and 0.2 inches in thickness and which includes a plurality of wire receiving openings. A plurality of Z-shaped stationary contacts are positioned inside the housing and a rotatable contactor is disposed inside the housing for selectively contacting the stationary contacts. Each stationary contact is positioned to overlie at least a portion of one of the wire receiving openings for locking engagement with a wire to be inserted therethrough. Each stationary contact includes a locking tongue, a spring finger and an intermediate arm, the intermediate arm linking the locking tongue to the spring finger. The locking tongue is connected to the intermediate arm at a first bend and the intermediate arm is connected to the spring finger at a second bend. The housing of the switch is configured to include a plurality of pairs of corners and a plurality of posts, one post being adjacent but spaced away from each corner. Each stationary contact is disposed in the housing with its first bend wedged in one corner in a pair of corners and extending around the post adjacent that corner and its second bend wedged in the other corner in the pair of corners and extending around its post adjacent that corner. Each stationary contact further includes a third bend in the intermediate arm, the third bend having an angle of about 130 degrees to about 140 degrees. The spring finger of each stationary contact comprises a straight member and a bent tip, the straight member and the bent tip forming a bend angle at the junction thereof of about 80 degrees.
