Have questions about a SparkFun product or board? This is the place to be.
I am using the SparkFun Servo Trigger to toggle a Radient servo between two positions.
I use a single pole single throw switch to activate the servo trigger board and a 100 watt 5 volt power supply to power the board and servo.
I have checked several times to make sure the board is getting exactly 5 volts.

It works great most of the time, however, I have noticed if the switch is toggled too quickly it causes the servo to twitch back and forth a couple of degrees very quickly. It basically sits there and quivers till I kill power or the servo releases the magic smoke.

Is this an issues with the Servo Trigger board?
Is there a way to fix it?

I used the exact setup for months when I first designed it and it worked great.
It was not till other people started to use it that this problem showed itself.
