Been scratching my head trying to figure out how to put the following circuit idea into practice with no luck.Basically i got a push to make pushbutton now when its held in the pressed position i want it to activate a relay when its released like a dead mans switch in a train ?
use a normally closed push button to wire a relay. when its pushed the contacts are open, when it released the push button comes to normal position making the path for the relay.
Want it to do is:
To start turn the circuit on
1.button not pressed nothing happens
2.button pressed and held and in that position (nothing happens) until it is released like a dead mans switch
