Posted this in the wrond section, so reposting here:
Complete newby to electronics, but have a basic understanding. Have an idea for a little project and tried searching the net and couldn't find a component or its technical term, what I am after is a component that when built into a basic battery operated circuit works as a "release" in that when the circuit is off the (say for instance pencil) is held, but when the circuit is switched on, the component (possibly a claw) opens to release what it is holding. Not sure of its technical term, so having difficulty finding anywhere that stock such an item. I'm only talking about a cheap item, basic device which opens when circuit is switched on, incorperated into a basic circuit powered by a 9v battery.
Thanks in advance! and sorry for the crude nature of the question.
