Re: Looking for Voltage Control Switch Ideas

We use a 22 mm Joystick made by Centsable --- Automation Direct.   It 
has a 3 position switch (momentary return) with center off and works 
great.  A nice black boot makes it look sharp. We also use their 
standard 22 mm industrial switches and matching indicator lamps (24 
VAC control loop) for our controls.  See it work at our Teslathon next week!!
