ABSTRACT:
A system and associated method for preventing damage to an adjacent wall surface of an electrically operated bed that utilizes a normally closed/momentarily open switch assembly attached to the bed frame at a location such that when the bed fame is maneuvered toward an adjacent wall surface, a head of the switch contacts the wall surface before any other part of the bed frame or a proximity sensor switch is activated when the switch head is in the prescribed range from the wall surface. The push button switch is in electrical communication with the bed frame operational circuitry. When the switch activated from its depression from thw all surface contact or its proximity to the wall surface, the electrical circuitry in the system circuitry is interrupted thereby stopping the operation of the bed frame from being maneuvered and preventing damage to the wall surface.
