Abstract

Una herramienta eléctrica que incluye un ensamble de interruptor de velocidad variable que incluye un potenciómetro que tiene un miembro rotable central que define un agujero con una sección transversal correspondiendo a la sección transversal del agujero del potenciómetro central de tal modo que el poste central puede ser alojado en el agujero central sólo en una posición relativa con respecto al miembro rotable central. El ensamble de interruptor de velocidad variable también incluye una cubierta de interruptor que tiene proyecciones que se acoplan por salto por resorte a agujeros designados provistos en una tarjeta de circuito de tal modo que la cubierta de interruptor y el circuito no pueden ser ensamblados incorrectamente. La cubierta de interruptor incluye un miembro de tope que se extiende a un hueco semicircular la rueda de control de velocidad para proveer topes mecánicos de tal modo que el movimiento rotatorio de la rueda de control de velocidad corresponde con la escala del potenciómetro. El ensamble de interruptor de velocidad variable también incorpora una disposición de retén integrada a la cubierta de interruptor y la rueda de control de velocidad e incluye una extremidad elástica, cuyo extremo es recibido en una serie de ranuras de retén en la rueda de control de velocidad en una posición angular deseada correspondiendo al ajuste de velocidad deseada.
