ABSTRACT:
A switch is provided with a moveable contact and contact carrier that significantly facilitates the manufacturing process necessary to make the assembly. The contact carrier is provided with first and second extensions that are generally flexible and associated with each other to provide a gap therebetween. In the preferred embodiment of the present invention, the second extension comprises first and second fingers that extend from the contact carrier. The second extension is provided with protuberances that permit a moveable contact to deform the second extension as it is moved inward toward the contact carrier. The extensions snap together after the complete moveable contact has moved into a predetermined space between the extensions. The assembly of the present invention permits the moveable contact to be permanently retained between the first and second extensions, but variable moveable in position within that containment to permit the position of the moveable contact to adjust to the position of fixed contact when the contact carrier is moved within a housing structure to force the moveable contacts into electrical communication with a pair of fixed contacts.
