Momentary switch - MSWH

    How about a switch which is only active while spark is applied thru pscn and goes inactive when the spark is gone.  this would make for simpler more reliable gates.

     A transistor? There is already transistor functionality in TPT (NTCT and PTCT)

    I should think that's what he was wanting.

    Problem solved. You can do it with NTCT and PTCT also.

    Maybe you don't have to think that, on the internet you can think what you want.

     what? "I should think" is a common expression approximately meaning "I'm pretty sure"...

    Thanks for all the response.  I know about cold/hot transistor function.  each of those are slow to respond and has to have 4 inputs.  1. "source" 2. "load" 3 and 4 control switching.  I would have just 3 control switching and have it very responsive.  while 3 (pscn) has spark the MSWH is on.  When spark on 3 is gone the MSWH goes off.  Not temperature dependent.

    Solutions:

    1. use ambient heat
    2. use cray/pstn
    3. use SWCH, and put the NSCN close to the PSCN
    4. cool/warm the semiconductor using FILT and a CLNE

    minecraft-physics, he wants ONE-PIXEL sized thing.
