This switch features “Bilge Pump” backlit label and contura style illuminated rocker switch. However it also includes a VERY useful alarm buzzer. Install a second float switch (higher than the one that triggers your bilge pump). If water reaches the second float (meaning your pump has likely failed) a visual and audible alarm will activate. Very handy indeed. Includes panel cut-out template and is IP66 rated. This switch does not feature a circuit breaker like others in the range, so a fuse or circuit breaker should be added in circuit.
