1. A voltage control device comprising, in combination:

  • a support plate having a front and rear surface;

    controllably conductive means for connection in series with an electrical load and having a control electrode;

    said controllably conductive means mounted relative to said support plate;

    control circuit means connected to said controllably conductive means for coNtrolling the conduction of said controllably conductive means in order to control the output voltage to said load; and

    an adjustable resistor constituting a component of said control circuit means;

    said adjustable resistor having a linearly movable control element;

    adjustment of said linearly movable control element causing the change in the output voltage to said load;

    said adjustable resistor being mounted relative to said support plate;

    said support plate having a straight, elongated slot therethrough;

    said linearly movable element of said adjustable resistor extending through said elongated slot and being operable from a position adjacent said front surface of said support plate;

    said support plate being of conductive material; and

    wherein said controllably conductive means, said control circuit means, and said adjustable resistor are each supported from said support plate, and are disposed on said rear surface of said plate.
