Abstract
A dimmer switch and dimmer system is described in which dimming for the entire system is controlled from a single device while on/off switching is controlled by individual devices at multiple locations. The main dimming device contains an alternate action switching circuit for opening and closing the gate circuit of a controllably conductive device. Each of the remote location switching devices consists of respective low voltage switches, each operable to operate the alternate action switching circuit in the main dimmer device and are connected thereto by wiring which carries only signal level voltages and currents. Each remote switch may be a wall-mounted switch containing a single, relatively large area push button which momentarily closes a short movement, low activation force pair of contacts when the large area push button is depressed by pressure applied to any portion over its surface.
