This is how to make a 'Release Switch', it detects when a switch is released sending a single signal pulse to the output. It can also be modified to have a delayed trigger after release. This may not be the most useful switch but I needed it in a level I'm working on so I'm sure other people can find a use for it. Plus it is really simple to make, all you need is a 'NOT' gate, 2 counters and a timer (the second counter isn't essential but prevented it from glitching). Components Set Up: Counter #1: Target Count = 1, Current Count = 0, Inverted = NO Counter #2: Target Count = 1, Current Count = 0, Inverted = Yes Timer: Instant - Target Time = 0.1s, Current Time = 0.0s, Input Action = Start Count Down, Inverted = NO _____..Delay - Target Time = Delay, Current Time = 0.0s, Input Action = Start Count Up, Inverted = NO Circuit Set Up (As in Image): - The Release Switch Input goes into the NOT Gate Input - The NOT gate Output goes into the 2 Counter Inputs - The Output of Counter #1 goes into the Timer Input - The Timer Output goes to the Reset of both Counters as well as the Release Switch Output http://img12.imageshack.us/img12/4442/releaseswitch.jpg Hope you find this useful, feel free to ask if you have any questions.

I made a similar sensor, called it the Signal Change Sensor (https://lbpcentral.lbp-hub.com/index.php?t=48824-LOGIC-TOOLS-Speed-Sensor-Signal-Change-Sensor)which sends out pulses on positive/negative signal switches. I used 2 timers, each set to "Start Count Down" and had each connected to their own reset input to create the pulse, and connected a the input to the first timer, and it's complement to the second timer. The main use of this I think would be to create synchronous systems (implement a clock interface)

Why you use timer to give the pulse? I would only hook NOT gate to counter that resets itself.

I tried using the self resetting counter, and for some reason it didn't work, at least for the thing I needed it for this seemed to be the simplest solution. It may be because the Counter resets itself too quickly or something, but when I tried that nothing happened

My release switch was a little different. Still works though ;]
