This is a multifunction switch.

The > input and > output mark the signal flow through the module.  When the switch is off, no signal is passed.

The t input allows you to chain together switches, controlling as many switches as you want from just one button.

The t output is the on (1) and off (0) state of the switch.

A -t output is provided for convenience.

The k output sends a number set by the two knobs on the module.  The top knob is A (on) and the bottom knob is B (off).

To change the switch’s function to momentary, enter the module, right click/tap on the switch and deselect “toggle.”
