Abstract
A sensing system is provided which senses an obstruction between a closure member and a frame, regardless of the direction of the input force to the sensor, such that when the obstruction is sensed to be between the closure member and the frame, the operation of the closure member can be controlled to prevent further closing of the closure member upon the obstruction. The sensing system includes a membrane switch assembly which changes resistance when a force component caused by the obstruction is exerted on the switch assembly.
