ATO Controllers |
Float Switches |
|||
A float switch is used to detect liquid levels. There are magnets embedded inside the float which activates a reed switch inside the shaft of the float switch. By default the switch is closed when the float is down. If you reverse the float, it will reverse the operation of the float switch. They are rated to 30 watts. We recommend using a relay (like we do in all of our ATO's) to carry the electrical load. If you have a reef controller (like a Neptune Systems Apex or similar) you can connect float switches to it then program it to turn outlets on/off based on the state of the switches. |

Horizontal 0.7 - 0.8” hole required for mounting (closer to 0.7 is a better fit). Your water level will be permanently set to approx 0.2” higher than the top of the hole. 2.5" extends into tank and 1" on outside of tank. 0.7" float diameter. 18" leads. Switch is closed when the float is straight and open when angled. Can be installed either normally open or normally closed. FYI our ¼” bulkhead requires at least a 0.73” hole so if you have your tank drilled with a ¾” hole or 19mm you could use a horizontal switch or a ¼” bulkhead |
