Abstract: A switch arrangement is disclosed which may be used with an enclosed fluid resistant container. A pin-like element is inserted through a wall of the container to actuate a switch contained within the container. Thereafter, the circuit is not easily deactivated. The switch arrangement includes a switch located within the container for activating a particular circuit function. The switch includes a mechanical trigger which is moved to effect the switch activation. A narrow switch actuator, such as a pin, is used for moving the trigger. A slide block is positioned between the trigger and a container wall for impacting the trigger in a single direction. A plug is placed in the wall and has an aperture therethrough for receiving the switch actuator, and the plug also includes a separate labyrinth path therethrough for passing fluid to the outside of the container. The aperture in the plug is structured such that the switch actuator fits slidably in the aperture and substantially seals the aperture.

Abstract: A chassis assembly captivation arrangement for an electronic apparatus is disclosed. Circuit boards are attached to a chassis bracket formed from a strip and having three linear segments preferably comprising a U-shape. The chassis bracket includes vertical support tabs and outwardlyextending flanges. The flanges slideably interconnect with entrapment members in a lower housing portion and the support tabs contact both lower and upper housing portions when they are joined to enclose the chassis assembly. With this arrangement the chassis and circuit boards are captivated transversely and vertically within the joined housing portions.
