One of the two common/pole pins for the momentary SPDT step switch. Adafruit states two of the four switch pins act as the common and connect to one of the throws when pressed; use continuity testing or the product diagram for exact PCB footprint orientation.
Second common/pole pin for the same momentary SPDT switch mechanism, provided as part of the four mechanical/electrical switch legs. Exact physical footprint orientation is diagram-dependent.
One throw contact of the SPDT switch. The common pins naturally connect to one or the other throw depending on button state.
Second throw contact of the SPDT switch. The product page describes the switch as momentary SPDT with two commons and two throws.
Positive side of the built-in red indicator LED in the step switch. Drive with current limiting.
Negative side of the built-in red indicator LED in the step switch.

SparkFun describes COM-09190 as a breadboard-friendly 12 mm square momentary pushbutton with a large button head and tactile click.
Most parts here are simple contacts: press or release, open or closed. A few outliers — rotary switch potentiometer breakouts, NeoPixel potentiometers, wiper plungers — carry separate wiring requirements worth checking before you order.
