Newb Switch question

[carlton M]

When referring to momentary switches: What is "normally closed" or "normally open"? Which do I need for building a mod?
And... Recommend a supplier.
Be kind, I know zip about this stuff, but have a head full of ideas (a dangerous combination!).

I think normally closed.


Nor open would be on all the time until you pressed the button.

Normally closed , Means that the switch will let power threw when not pressed. Or it is on unless the button is pressed. When the button is pressed the switch is turned off. Normally Open means the opposite the switch is off when not pressed and on when the button is pressed. Normally Open switches are used the most in mods. But there are some regulators you can use a Normally Closed switch with. Digikey and Mouser are two electronic supply stores that have tons of switches to choose from.

I thought it was just the opposite, normally open no current goes through until you press the button and close the circuit.

normally closed == not press-- current flow
normally open ==not press --no current flow
