Release Switch [Tutorial]

[un-imaginative]

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



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 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 ;]
