55' sailing cat. Lot's of bilges, including two showers, many compartments. This is all good, and most of them have their own bilge pump
I replace the rule bilge pump
switches somewhat often. It's not just the trouble, cost and time, but also that there is no warning other than ... the water is suddenly found NOT to drain from a shower
. Starboard head
is mainly used for #1 visits, with only hand washing
. It takes many hand washes for bilge
pump to activate - so we don't notice when the switch "best before" is over.
Used three hours now, to research
online - any other switch that will last longer? Was drawn to the Johnson solid state switch - but despite solid state and no moving parts
- still confused by very contrasted reviews
. A mix of one star and five star ratings! Also, I don't understand if these switches need to be powered separately (what else drives the electronics
My vessel is 24V btw - usually only a question of pump selection, not switch.
I just want a simple on/off switch solution, which is likely to last more than a year.
I was thinking of doing a quad setup: 4 switches in a parallel - seriel setup. This would mean if one single
switch is not switching on, or one is not switching off, the system would still be working (but still no warning). This would delay the time until replacement, and guard against both constant on and constant off. Not all locations are suitable for 4 pumps, though, and it would cost a great bit to install.
Is there ... one switch to end-all of these common problems?
