Abstract
Abstract The specification discloses a miniaturized multi-position slide switch adapted for low voltage, low current applications, for example, so-called ''''shirt pocket'''' electronic calculators employing printed circuitry. Switch control elements of uniform configuration are arranged in a row in facing pairs in an insulating base, while an insulating cover for the base carries a track for a sliding contactor having a spring-biased steel ball. The base has a central longitudinal groove of V-shaped cross section in which the steel ball rides. Detenting is accomplished by a declining bevel or ramp connecting the V-groove to the Vshaped seat formed between the pairs of switch contact elements. One of the pairs of contact elements has a connector biased into normally closed contact therewith. At one extremity of its travel, the sliding contactor engages the connector and disengages it from contact with the contact elements. A dust shield in the form of an endless tape longitudinally surrounds the base and cover and has an opening through which the handle of the sliding contactor extends. The tape shield is thus shifted in an endless path by shifting of the sliding contactor.
