Roca CT41 Windscreen Wiper Control Unit

The Roca CT41 wiper control unit is the best solution when you want to control a single wiper motor without mounting separate electronics boxes on the boat — all control functions are built straight into a switch that fits most standard switch panels, for a tidy, space-saving installation. The unit supports intermittent wiping at three settings (2, 4 or 8-second delay) to suit conditions, slow or fast wiping (requires a two-speed wiper motor), and a wash function — hold the button for one second to trigger the windscreen wash cycle.

The CT41 suits low-power wiper motors, including Roca's own W10 and W12 models. It also has a parking switch, which always returns the wiper blade to the same rest position, and a built-in 4A automatic fuse, so no separate fuse is needed during installation. The 10–30V operating range suits both 12V and 24V systems.
