A Button Switch
A SPST (Single Pole Single Throw) Button Switch can be used as a trigger. There are three types (1) momentary normaly open (off) - the connection is made as long as you press the button, (2) momentary normaly closed (on) - there is no connection as long as you press the button, and (3) Push on/off - push once and there is a connection. Press again to turn the connection off.
The longest run (length of wire) from an audio soucre or a 1AMP 12VDC power source that I am confortable with is 50 feet. More about this latter - maybe.
Get a bunch of the type (1) momentary normaly off. Buy in bulk. Shop wisely.
Example of a Simple Button Switch Application
A Button Switch has been placed on one of the wires from the power supply to an air valve. When the button is pressed, the air cylinder will pop up.
Also see How to Pop Up for another example of a button swith application.
