  • Patent number: 4939320
    Abstract: A self-setting switch-actuating assembly includes a pair of cam members and a rotational motion transmitting shaft. The cam members are mounted on the shaft. The shaft is rotatably mounted between a pair of switches and is connected to a rotatable device whose rotational movement will cause rotation of the shaft and will stop in response to reaching angularly-displaced limits. The cam members are mounted on the shaft one above the other with each cam member aligned with only one of the switches and movable along a rotational path toward and away from a predetermined actuating position relative to its aligned one of the switches in response to rotation of the shaft. Also, each cam member is mounted on the shaft so as to be capable of stopping movement in response to reaching its predetermined actuating position and relative to continuing rotation of the shaft thereby permitting a predetermined degree of overtravel of the shaft relative to each of the cam members at their respective actuating positions.
