Which switch? The factory gauge selector switch is only a two-position unit.
If you mean an electric selector valve, the same thing applies, Both the motorized type and the solenoid type are only open or closed.
The motorized type stays in position when the electricity is turned off. The solenoid type (simpler and cheaper) goes back to the default setting when the key is turned off, or the switch turned off.
You have one you're trying to trouble-shoot, or planning on installing one?
