Abstract
A door panel position sensor assembly for a transit vehicle is provided which comprises a door mounted actuator device and a vehicle mounted switch operating mechanism which is mounted adjacent to the path of travel of the door and is actuated by the door-mounted actuator device during movement of the door between open and closed positions. The switch operating mechanism comprises a signalling switch whose switching state indicates the position of the door and a single actuator lever which is movable by the door mounted actuator device between first and second positions to control actuation and de-actuation of the switch. A spring arrangement is located between actuator arm and the signalling switch which assists in toggling of the actuator lever and which, under the control of the actuator lever, engages the switch to provide actuation thereof. The door-mounted actuator device includes a first, rigid actuator and a second, directionally flexible actuator which is spaced apart from the first actuator in the direction of travel of the door and which prevents damage to the switch operating mechanism when the latter is reset, due to inadvertence or vandalism, to the non-normal positio…
