The graphic on this page shows a arcade type pushbutton.  It actually has an 
illuminated pushbutton.

At just the right time before the spring rush - our shadow wall stopped 
working.  I am too worn out to spend much more time trying to fix it - does 
any body know where we can by the flash and trigger unit?  We currently us a 
motion sensor to trigger a timer that counts down from five then flashes.

Thanks
