Abstract: A selector is provided for varying the number of coins needed to permit operation of a coin-operated mechanism. The mechanism has a coin chute, a key-operated rotary actuator by which the mechanism may be selectively operated, and a coin-feeling finger arranged to permit operation of the actuator when a coin is sensed as being in a predetermined position within the coin chute. The selector includes an intermediately-pivoted operating arm mounted on the coin chute and having a nose portion engaging a cam on the actuator. A selector lever is pivotally mounted on the arm and may be moved to any of three discrete positions relative thereto. The arm carries two stops which are moved to coin-holding or out-of-the-way positions at each of the three relative positions. By selectively adjusting the position of the selector lever relative to the arm, the mechanism may be adjusted to require deposit of one, two or three coins before the mechanism may be operated.
