An electrical switch connector assembly, for mating with an electrical switch, comprises a housing having a plurality of electrical contact members disposed therein, wherein each one of the contact members have insulation-piercing members formed upon first end portions thereof for engaging electrical wires, and leaf-spring members formed upon second end portions thereof for engaging prong contact members of the electrical switch. A cover member is snap-engagingly mounted upon the housing so as to cooperate with the housing in retaining the electrical wires mounted therein, and a strain relief member is also snap-engagingly mounted upon the housing so as to co-operate with the cover member in providing strain-relief characteristics to the electrical wires.
