I have a multi-pin connector that I would like to be able to turn off with a single switch. How would I do that?
The situation is that there is a multi-pin connector cable (like an RS-232 connector) with two outputs. So, the cable will fork. One connector is permanently connected to a monitoring system which is always on. The other connector is free-standing and is only used for occasional test purposes.
When the test connector is used, the monitoring connector has to be turned off because otherwise it will send commands and electrical signals down the cable constantly. So, basically I need to switchover the cable from the monitoring device to the test connector.
Now, of course I could install a small switch on every wire in the cable, but it seems silly to install 24 switches or whatever. Is there a way to make all the wires go one way or the other using just one switch?
Note that it does not need to be either/or, I just need to turn off the connection to the monitoring system when required. I cannot do this by unplugging it because the monitor is installed in a panel that takes over two hours to disassemble, so unplugging it is not a good solution.
