Sealed housing for a remote switching device |
摘要 |
A housing assembly (14) for protection of an enclosed printed circuit board (12) with a surface mounted dome switch (18) is disclosed. Various construction details are developed which provide sealing under a variety of atmospheric conditions. In one embodiment, the housing assembly is comprised of an upper portion (22), a lower portion (26), and a one piece, continuous diaphragm (30). The upper portion has an aperture (24) for engagement of a button actuator (20) by an external force. The diaphragm, composed of an elastic material, provides a sealed cavity (32) for the housing and permits substantial equalization between the internal and external pressure of the sealed cavity.
