Abstract: A patient support apparatus includes a frame and an electrical system coupled to the frame and operable to operate an electrical function of the patient support apparatus. An endboard is removably coupled to the frame by a coupling mechanism that provides an electrical connection to a mating coupling mechanism of the frame. The endboard has a user input in electrical communication with the coupling mechanism so that an input received from a user at the user input is communicated electrically to the electrical system via the electrical connection to operate an electrical function of the patient support apparatus.
