    Abstract: A work platform includes a floor structure having a width dimension and a depth dimension and a safety rail coupled with the floor structure. A control panel area is cooperable with the safety rail and includes a sensor support bar having a top cross bar extending along the width dimension and side bars extending substantially perpendicularly from the top cross bar. Each of the side bars includes an upper section extending from the top cross bar inward in the depth dimension to a bent section, and a lower section extending from the bent section outward in the depth dimension to the safety rail. A platform switch that is configured to trip upon an application of a predetermined force may be attached to the sensor support bar. A switch bar may be secured to the control panel area, and the platform switch may be attached to the switch bar.
