Abstract

Switch device including an enclosure having a pivot or shaft arm extending across the enclosure with a distal arm attached thereto for selective contact to move the shaft to indicate the presence of an object. The pivotal shaft carries a actuator device for rotational movement with movement of the distal arm, a stop device connected from the inside surface of the enclosure extending toward the actuator device to engage the actuator device and limit the movement of the actuator device in a first direction, a sensor device normally located in proximity to the actuator device when the actuator device engages the stop device, a generally oval elastomeric spring device attached to the inner surface of the enclosure and adapted to normally to engage the side of the actuator device opposite the sensor device to bias the actuator device to engagement with the stop device and to allow the movement of the actuator device away from the stop device and the sensor device upon engagement of an object with the distal arm.
