A system and method for the alignment of an insulation piercing contact within a two piece switch housing with an insulated electrical wires disposed within the housing. The housing is comprised of two halves whereby when the two halves are brought together during assembly, the insulation piercing contact pierces the insulation of the electrical wires and forms an electrical connection between the contact and the wires. Proper alignment between the insulation piercing contact and the insulated electrical wires is ensured by providing extended prongs on one half of the switch housing. On the other half of the switch housing, channels are provided and arranged to slidably engage and mate with the prongs prior to contact of the electrical wires with the piercing contact. The prongs and channels fix the relative alignment of the contact with the wire before piercing occurs and ensures consistent location of the electrical connection formed during assembly of the switch housing.
