Abstract
A circuit board provides a first elevation adapted for printing and bonding of conductor and resistor traces and monolithic ceramic capacitors, and provides through holes adapted for locating conductors. A second elevation is adapted for location and containment of a semiconductor quadrac. A third elevation is adapted for location and containment of a circuit board which is selectively adjustable through an R-C network coupled between the semiconductor quadrac and an input power source. An electric phase control uses mechanical movement for actuation. Provision is provided for mounting the phase control mechanism and the circuit so as to be manually accessed. A planar switch cover plate is adapted for sliding engagement, in parallel juxtaposition, with the mounting devices, the switch cover plate further adapted for engagement with the phase control mechanism for actuation through sliding engagement.
