Abstract: An enclosure for electronic instrument panel circuitry including a circuit board, a front housing with rear lower and upper locking flanges, and a two part case, preferably articulated at the rear for clamshell operation. The case has flanges on each part for interlocking with the housing, without separate fasteners. The circuit board is located in the case and connected to the housing before the case is closed. Support members molded in the case hold the circuit board in place and a single screw further secures the circuit board. A second circuit board on the rear of the housing is trapped by its margin between the housing and case, and held without screws.

Abstract: A switching apparatus providing both linear momentary and rotary switching, including a carrier element disposed within a switch housing and activated by the rotation or linear displacement of an operator manipulated button. The carrier is supported on a central transparent shaft which pipes light to a button-mounted indicator from a lamp disposed behind the switch apparatus. The carrier element supports rotary and linear contact rings in relation to a coplanar set of stationary contacts formed on the bottom of the housing. The rotary contact ring is resiliently biased into engagement with the stationary contacts, and is keyed to the carrier element for rotation therewith, defining a rotary travel switch. The linear contact ring is resiliently biased away from the stationary contacts and into engagement with a shoulder formed on the carrier element shaft, defining a linear travel momentary contact switch.
