Abstract: An insulating switch base (16) with a top (17), bottom (18) and an edge (19) has configured openings (20) through the top (17) and one edge (19) for a conductor. A conductive switch (10) lead frame (22) has proximal ends (24) with insulation displacement connectors (25) bent in the openings. A resilient member (26) on the frame has a moveable contact and is conductively associated with a connector. A contoured arm (27) on the frame is distal of but conductive with another connector. The arm is spaced from the member as an open contact capable of momentary engagement. A frangible area (28) on each frame is between the member and the arm. Recesses (30) in the top (17) support (41) and retain the frame. A slot (35) and barbs (36) on each connector receive one conductor and secure in an opening after aligned installation in an opening, seating of the frame in its recess and severing the area over a passage in the base. A membrane attaches over the frame and a molding is applied about the membrane leaving the member open. A method of assembling the switch (10) having a cable (13) with conductors with a base. Driving conductors into the openings to bend into sections (21) and pressing the cable (13) into a channel on the base are steps. Forming and installing a frame with contacts (12) and connectors in recesses (30) to hold the frame with contacts (12) normally open but capable of closing are steps. Displacing the insulation on the conductors with connectors while separating the contacts (12) by severing areas of the frame and attaching a membrane over the frame and base are steps. Trimming excess conductors to prevent protruding from the base and encasing the assembled switch (10) in an insulator are steps. A tool for the assembly of base and frame has a support (41) to position and retain the bottom (18) aligned with the frame. An inserter (42) and a holder (43) force and bend each conductor in its section (21). A carrier locates the frame relative to and in alignment with recesses (30) in the top (17). Lugs (45) engage connector apertures (34) to drive each into an opening and chisels (46) cut areas over passages (37) on the base. Preset protuberances engage and set the arm when seating the frame so the dimple (31) engages and sets the switch (10) gap.
