Abstract
A switch device has a housing with a chamber therein including at least one surface, and terminal members and switch elements are arranged in the chamber for electrical engagement and disengagement, respectively. A pedestal is integrally formed with the at least one surface and has a free end predeterminately spaced from the at least one surface. The terminal members are engaged with the free end and predeterminately extended beyond the marginal edges thereof so as to shield at least a part of the pedestal from the depositing thereon of any minute conductive material particles emanating in an arc blast from at least one of the terminal members and the switching elements upon the electrical disengagement thereof under load thereby to prevent the establishment of a conductive path of the deposited particles across the pedestal between the terminal members and the at least one surface. A method of making a switch device is also disclosed.
