Phone jack / plugs .... anatomy & pics ....( link )

Found this link buried in another group .... best I've seen for jacks & explanations . Link opens in new browser window .... http://gaussmarkov.net/wordpress/parts/connectors/14-phone-jacks-and-plugs/ edit ... take note of the last (bottom) illustration .... easy way to "on/off" a CBG amp without using a switch . Wire the circuit ground (everything except the battery - ) to the green "ring" contact and the battery - to the gray contact , and when a plug is plugged in , the sleeve connects the battery .
