Notes on switches:
2 Position & 3 Position Double Throw are different.
DT switches (whether SP or DP) can be 2 Position ON-ON  (Toggle in the Up or Down position) or 3 Position Center Return (ON)-OFF-(ON) – (Toggle Momentary Up or Momentary Down, Center return Off) with variations of Maintained or Momentary states.

Note that the (Parenthesis) = the Momentary State whether it be a Toggle Switch or Momentary Push Button. For example an Off-(On) Momentary Push Button is normally Off, Push On. An On-(Off) is normally On, Push Off.

The example farm belt conveyer circuit above consists of a 2 Position DPDT Maintained On-On toggle switch followed by a SPST Momentary Off/(On) Push Button in series with a 3 Position SPDT Momentary (On)-Off-(On) Center return toggle switch.

Although the Up/Dn switch in the schematic is a SPDT (O-F-O) I would use the DPDT listed below which provides an extra set of contacts for flexibility. For example a DPDT switched can be used for a SPDT, SPST or DPST circuit.
