DMX Lighting System

The momentary switch used was rated for 10A for safty. If the switch was rated for too small a current, the instantaneous current for the first millisecond would fuse the switch contacts together. To achieve objective 3, some sort of switch that can vary current must be used. The posibilities are potentiometer, pulse width modulation,

or a triac circuit (light dimmer). The light dimmer is represented by the potentiometer in the schematic diagram. The only problem with this circuit is that there is no on/off switch any more. To incorporate an on/off switch, I have chose to place it in series with the dimmer (shown below).
