Abstract
A conventional light plate for a systems control panel is mounted on a machined front plate which, in turn, is maintained a predetermined uniform distance from a front printed wiring assembly (PWA). A plurality of systems control devices including one or more of switches (toggle switches, rotary switches, push button switches), rheostats and annunciators are mounted on the front plate and front PWA. Each of the systems control devices has one or more solid state elements mounted on the PWA. For example, the switches carry small magnets which, by manipulation of operating switch levers or knobs, move into and out of close proximity to magnet sensitive switching devices mounted on the front PWA.
