Abstract

The three position, push to slide, multiple position slide switch has become a paging industry standard switching device. The switch is currently widely used at Motorola end by most of our competition. The inherent fact that the mechanism is being pushed and slid at the same time suggests a possibility of contamination.

MULTIFUNCTIONAL SLIDE SWITCH DUST COVER DESIGN FOR Z-AXIS ASSEMBLY AND INSULATION PROTECTION

by Carlene Gayhardt and Jeff King

   The three position, push to slide, multiple position slide switch has become a paging industry standard switching device. The switch is currently widely used at Motorola end by most of our competition. The inherent fact that the mechanism is being pushed and slid at the same time suggests a possibility of contamination.

   To prevent this wntamination, as much as possible, a mylar dust cover must be inserted between the switch knob and the plastic housing of the primary paging device. lb aid in the assembly of the final product, the dust wver must be assembled to the switch prior to final assembly of the complete pager. In the past, this mylar piece or pieces have been free floating on the knob with no apparent method of retention to the basic switch housing. This lack of retention in the relative Z-axis has presented an ongoing problem at final assembly. The problem occurs when the switch knob and dust covers must be separated at final assembly. In other words, the switch knob mu.4 remain to the outside of the pager to promote easy user operation, while the dust wvers must remain inside a boundary wall, which is an integral part of the primary pager housing. At this point, in a typical clam shell housing, all of this must occur between two halves of a housing, namely the front and back housings. This is a basic...
