Johnson Pump Automatic Float Switch

• For full automatic bilge pumping operation, connect the automatic switch to a bilge pump.
• Has a time-proven micro switch without mercury.
• When water exceeds the acceptable level, the pump is turned on by a rolling steel ball, which changes the pressure on the micro switch.
• Attaches through the clip on “T-slot” and can be used with 6, 12, 24 or 32 volt systems.
