Abstract: Surge protection assemblies, each comprising an assembly housing, an assembly circuit board, a module, and conductive elements (each with a region electrically connected to a contact region of the assembly circuit board, and a region outside the assembly housing); The module comprises plural varistors inside a module housing, a module circuit board, and module terminals each with a region inside the module housing and electrically connected to circuitry on the module circuit board, and a region outside the module housing. The surge protection module is movable as a unit between an engaged arrangement (each of the terminal second regions is electrically connected to a respective terminal connection region of the surge protection assembly circuit board) and a disengaged arrangement. Also, surge protection modules, electronic assemblies each with a surge protection assembly, and methods of installing a surge protection assembly to a plurality of circuitry conductive elements.

Abstract: A touch-screen control panel interface has a dielectric flat or curved front panel and a printed circuit board with a front side and a reverse side which is the component side. Alphanumeric display module(s) or an LCD display and optional protective cap mounted on the reverse side of the circuit board are visible through window cutout(s) on the board. An array of LED indicators can be mounted on the back side of the circuit board and visible through cutouts in the board. Metallized capacitive pads on or adjacent the back side of the front panel at touch locations permit selection of various modes, functions, and settings. These pads may be formed on the flat front side of the circuit board, on the back of the front plate, or on an intermediate membrane. A microprocessor is connected with the various components and with capacitive pad. Icons may be printed onto the flat panel, in registry with the metallized capacitive electrode pads.
