I need a connector with the same functionality as a 3,5 mm earphone jack
that opens a existing circuit and connects a new one.
Just like a legacy earphone that disconnects a speaker and connects the earphone instead.
Or the connector of a power supply, that disconnects the battery when plugged in.
But I want something more robust, like an XLR connector.
Are such connectors available, and what are they called?
Thanks for comments or suggestions.
