COM A
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.
Type · Unknown
COM B
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.
Type · Unknown
THROW 1
One throw contact of the SPDT switch. The common pins naturally connect to one or the other throw depending on button state.
Type · Unknown
THROW 2
Second throw contact of the SPDT switch. The product page describes the switch as momentary SPDT with two commons and two throws.
Type · Unknown
LED anode
Positive side of the built-in red indicator LED in the step switch. Drive with current limiting.
Type · PowerVoltage · Red LED forward voltage about 2.1V to 2.3V, 20mA max per Adafruit product page.
LED cathode
Negative side of the built-in red indicator LED in the step switch.
Type · GroundVoltage · Red LED forward voltage about 2.1V to 2.3V, 20mA max per Adafruit product page.
