A manual selector includes a frame fixedly seated on a base forming oppositely opening internal grooves. A slide is slideable lengthwise in the grooves between discrete selective positions. A position identifying colored surface of the base is visible through a slot in the top of the frame for distinguishing between the selector positions. The slide includes a plurality of feet at opposite sides of the slide. The feet contact the colored base surface only at the opposite margins of the surface. A slide-locating assembly includes an interengageable member carried by the slide and a plurality of cooperating interengageable members carried by the frame. The engagement of the slide interengageable member with one of the frame interengageable members defines one of plurality of selective positions.
