Create an SVG image of an interactive SVG button, from a rectangle that includes linearGradient & radialGradient and drop shadow.
DISABLED DISABLED OFF OFF ON ON
Scenerio:
If the motor's starter is in its manual OFF or ON selection, the SCADA ON/OFF button is shown as "DISABLED". It cannot be selected by the SCADA operator.

The user places cursor over the button, then toggels the button to ON(green) or OFF(red). The button displays "ON" or "OFF" text. Note: Added button click sound.

A 'feed' line leaving the bottom of button displays as dashed/red for OFF and solid/green for ON. (It is intended to connect to an image representing where the feed connects.)
