ABSTRACT:
A frequency selector (tuner) employs a turret to select the position of a slide member that is coupled to a variable reactance. The slide member is moved away from the turret by depressing an operating member and returns to the turret when the operating member is released. Depressing the operating member rotates the turret concurrently with the movement of the slide member, but interference between the slide member and cooperating position setting elements that project from the turret is avoided by a displacement mechanism on the slide member. The projection of the position setting elements is adjusted by turning the operating member. A further operating member is provided for turning the turret in opposite directions, the final position of the slide member being set by depressing the first-mentioned operating member.
