switch, relais and push button
Hello all,
I am trying to understand a ususal read defoger switch a relay of a car. This switch is a push button, the power is initially at position off, you must turn the ignition on to be able to tunr the defoger on, then at this point it is posible to turn it on or off. What would I need to build a similar circuit ?
A push button (momentarily contact on when pushed)
A relay ...
I would know how to build this circuit with a on / off switch but the push button ?? :?
Thanks a lot !!
