Built-in fuse holder and internal illuminated switch with three positions (AUTO, OFF, MAN). When the automatic mode is selected, the three boat switches are illuminated. It also has a "fail-safe" spring that returns the switch from the "hand" to "off" position so that the pump cannot be accidentally left open.
