Abstract: An electronic device for use in a health care setting has a rigid enclosure assembly formed by a rigid shell and a rigid printed circuit board carrying circuitry for operating the device. A switch dome layer and an overlay are independently attached to the device but not to each other, whereby the overlay may be removed without disturbing the dome layer and a better tactile response is achieved.

Abstract: A normally closed dome switch comprises a printed circuit board including a switch trace having first and second contact areas electrically insulated from one another, and a conductive switch dome having a central portion spaced from the printed circuit board and a plurality of contacting portions extending from the central portion such that each of the first and second contact areas is contacted by at least one of the contacting portions when the switch dome is unpressed such that the unpressed switch dome forms a closed switch between the first and second contact areas. The switch dome is resiliently pressable to urge the central portion toward the printed circuit board and pivot the contacting portions about a corresponding fulcrum to remove the plurality of contacting portions of the switch dome from contact with at least one of the first and second contact areas to open the switch.

Abstract: A strain relief device for connecting a cable to a housing of an electronic device comprises an elongated elastic sleeve including first and second opposite ends and an axially extending sleeve passage, and a rigid insert including a first portion surrounded by the sleeve, a second portion protruding from the second end of the sleeve, and an axially extending insert passage aligned with the sleeve passage. The second portion of the insert is shaped to be non-rotatably received by a wall opening of the housing through which the cable passes, and may be D-shaped to mate with a D-shaped wall opening of the housing to prevent relative rotation. The second portion may carry a removable retainer, such as a C-shaped clip, for engaging a wall of the housing to prevent withdrawal of the insert. The invention facilitates serviceability and eliminates overmolding of a strain relief device onto the cable.

Abstract: A low-profile locking clip is installable on a surface-mount header of a printed circuit board to secure one or more inserted plug connectors in mating engagement with the surface-mount header to prevent unintended loosening and disconnection. The locking clip comprises a plurality of catch members that engage with respective lead pins of the surface-mount header and a top wall that includes one or more recesses for receiving a detent tab on a corresponding plug connector to prevent withdrawal of the plug connector.
