    In what regard?

    The bus coupler is a small device, typically grey and purple, that has some terminals for wiring in dry contact style switches. It also has a C-Bus connection.

    A C-Bus switch is a complete unit that mounds on the wall with buttons and indicators. It has a C-Bus connection on it's back.
