This is probably something very easy but I just can't figure it out how to do it. I want to power my circuit from a battery for a 0.1sec time period using a switch (a push-button in real life). I have tried time controlled switches but the third nod won't accept any type of input signal.

Thank you!

The problem with the Time Controlled Switch is that it is basically only a one shot operation.

You have much more freedom if you use a Voltage Controlled Switch and drive it from a PWS() voltage source that toggles the switch at the times you specify in the PWS().

This is an example of how to make a SPDT switch this way:

and this is the same SPDT switch in use:

There's some helpful background in this thread:

Here is my idea https://www.circuitlab.com/circuit/tp6qt6/time-swithc-temp/ one switch (SW1) turns on at 'StartTime' then the other switch (SW2) turns off 0.1s later. here is a picture so I can delete the circuit some time

Thank you all. It worked out well)
