The reverse scan readers I have worked with had a switch inline with the LED. It never caused a thump.I read somewhere on here that you increase the life of the LEDs by switching them off. Just became a habit, close the dowser, change the sound to N/Sync and switch off the LED.

The thump that you talk about is common when you switch the LED with the changeover shutter. Control it with the motor and this is eliminated. I dont know why but the newer Kiniton FP30s switch the LEDs with the changeover - we mod our ones to follow the motor relays.

I have seen both lazer and led switched by relay and switch.
the change over is unnoticable, switch off and switch on is as good as in built electronic C/O systems. [Smile]
