RULE ECO SWITCH 24V float switch

Automatic switch for bilge pumps – mercury-free, operates using air pressure and is therefore environmentally friendly – when water rises in the bilge, it pushes air into the small tube connected to the switch, creating sufficient pressure to activate the microswitch – all electrical connections are above water and there are no moving parts – provides exceptional reliability and safe performance
