- Float Switch - Horizontal Mount
Recommended for water applications like level controllers, auto top systems or other aquarium uses
- Normally closed or normally open (see more)
- 14” leads (22 gauge wire)
- M16 straight threading - includes nut and silicon o-ring
- 5/8" Mounting hole required
Mount with wires outside of chamber
Horizontal Mount Float Switches are great for:
- General water level control applications
- Aquarium top-off applications
- Humidification/de-humidification applications
- Hydroponics project
- Water features
- Air conditioning drain pan applications
Don’t use in heavy duty applications like sewage pumps.
Great for water. Check your fluid's specific gravity.
The wires complete a circuit when the float is down. You can reverse the operation by removing the clip, turning the float upside down and replacing the clip.
A pump rated at just 5 watts can destroy a float switch rated for 50 watts, locking it in the “on” position and pumping a lot of water where you do not want it.
The magnetic reeds enclosed in liquid level sensors are extremely reliable and long-lasting when utilized properly. Failures are nearly always a result of current overloading. Pumps, solenoids and many other devices that require control by a liquid level sensor carry "steady state" current ratings. These devices can draw ten times (or more) their steady state power ratings on start-up or shut-down. When the reeds inside our switches are exposed to this kind of "spiking voltage" they can overheat and become deformed. In some cases they may even weld together or break off, causing the switch circuit to remain closed (or open) regardless of the level of the float. Deformed reeds can also function intermittently, causing problems with troubleshooting. A 50-watt float switch can be destroyed by a pump rated at 6 watts and, unfortunately, it may take many cycles before the failure occurs.
Because they can destroy an otherwise very reliable float switch, care must be taken to completely isolate the switch from the current drawn by pumps, solenoids or other devices subject to spiking voltage. Resistors or diodes may be used, but the most common solution is to utilize a circuit board or a relay.
In the illustration, a relay acts as a switch for a pump, thereby isolating the float switch from any spikes that the pump may draw. The float switch turns the relay coil on and off. In this way, the only current handled by the float switch is that small amount required by the relay coil. Please consult with your relay supplier to assure that the relay current requirements are well within the specs of the float switch.
Is good product By Leo rodrigues on 4/24/2016Leo rodrigues would recommend this product to a friendThanks work perfect
Works Perfect By Joe on 2/5/2015Joe would recommend this product to a friendWorks as advertised. Easy to install. Black color matches my setup better than white.
Perfect float switch By Opwan on 5/1/2014Opwan would recommend this product to a friendDoes what it's supposed to do, great product
Great quality By Phillip on 8/9/2012Phillip would recommend this product to a friendHas the plastic nut, some of the others don't. I especially like the black color, doesn't start looking crudy as fast as white parts do!
Can this be connected to vertex cerebra?
What size drill bit is needed for this?
Is this switch compatible with the neptune apex breakout box for use with things like water level monitoring?
You could certainly use these with the Neptune breakout box.
If used with Neptune apex BOB, do I need the relay that you talk about in the product description ?? Thanks!
Do you sell a 120v relay 3 prong plug that can be utilized with this device to turn a pump on or off?
We do have a relay but it is part of an ATO kit that includes a standard vertical float switch. You can use the horizontal switch in place of the included switch.
I hope this helps!
Have a great day :)
