Abstract: A panel-mounted fuseholder unit for accepting fuses is provided with integral snap-in mounting means for securely engaging the panel in regions peripheral to a panel mounting aperture when mounted preferably from the rear of the panel so that the fuseholder can be pre-attached to a wire harness. Complementary preferably latched side-engaging means allow an interlocked side-by-side array of fuseholder units to be fabricated and panel mounted by their individual mounting means. The side engaging means are disposed sufficiently away from the engaged panel so that no special contouring of the aperture is necessary to provide clearance.

Abstract: An electrical device, which preferably forms a plug-in relay unit, includes a terminal board assembly most advantageously formed by a pair of insulating plates made of thermoplastic material and between which are clamped the intermediate laterally extending portions of terminal blade members having outer portions projecting transversely beyond the outermost plate constituting a base plate and transversely innermost portions projecting beyond the innermost plate constituting a clamp plate. One or more of the terminal blade members carry stationary contacts on the inner ends thereof. The insulating plates are held secured together and a bobbin assembly having thermoplastic pins are passed through apertures in the base assembly and ultrasonically vibrated to weld the same to the walls of the apertures.

Abstract: A double buzzer assembly comprises a housing assembly including a main housing body having a parts-receiving opening confronted by a cover removably interlocked with said main body portion and first and second buzzer units mounted in said main body portion in spaced relation in a direction parallel to the plane of the opening and adjacent to a rear sound emitting wall on the opposite side of the main housing body from said opening.
