You are correct APDahlen,
CTS has another DIP Switch, 206-124 CTS Electrocomponents | Switches | DigiKey
The datasheet explains better for this one how these switches need adjacent pins to be connected on the circuit board to make it a SPDT.
And here is a diagram of how the switch works if you tie two pins together to make it a SPDT. It doesn’t matter which side of the switch you tie the pins together.
