This is a release switch, when grabbed then released; the output activates for .1 seconds. The timer is set to .1 seconds so when you release you can grab again in .1 seconds. The reason there's a timer is so there's .1 seconds when you are not grabbing and when the selector says you grabbed. It's hard to see, but the timer output goes to the first input of the selector. I use the selector as a "permanent switch", when you grab it turns the permanent switch on, (output 1) then when you're not grabbing and the permanent switch is on, (output 2) the And switch output is on for .1 seconds then it resets. So for this you can plug the And switch output to a light or something, or you can have a button instead of a grab switch.
I hope this helped!
