[0001] This application claims priority to provisional patent application serial number 63 / 531,401, filed on August 8, 2023, the entire contents of which are incorporated herein by reference. Technical Field
[0002] The present invention relates to a floating switch; and more specifically, to a tethered floating switch. Background Technology
[0003] Float switches come in various configurations. Many tethered float switches are mounted on the pump itself, with the cable length determining the water level and switch operation. Tethered float switches can shorten operating time by reducing cable length and extend it by increasing cable length. Some tethered switches are mounted on a pole separate from the pump. These pole-mounted switches can be loosened with screws, and their height can be adjusted to the desired floating position. Other types of floats are directly built into the pump and cannot be adjusted, so pump operation is determined by the float's set height. Electronic switches offer flexibility because they have two independent switches that can be positioned in multiple locations within the tank or pool. These switches can be positioned close to or far from each other to control pump operation. There are also electronic switches with diaphragm or other sensor controls that can be adjusted for specific levels to control pump operation. Known disadvantages of the equipment
[0004] The known drawbacks of tethered float switches are that they are mounted on the pump and can only be adjusted via cable length. If floating on a separate mounting rod, the installer must insert the float mechanism into the tank or container, test the position, and then reach in to adjust. The float can be adjusted along the length of the rod, but this is a more laborious and complex process. Current disadvantages include a lack of flexibility in overall adjustability and the need for further validation to ensure the pump and switch are fully operable to the desired level. For two-piece float switches, the sensor can be positioned in various ways, and pump operation needs to be checked. A clamp may need to be adjusted to ensure the pump turns on or off at the correct water level. The installer needs to reach into the tank or container to adjust. Other diaphragm or electronically sensed controls typically require pre-logic control and are less flexible once set in the clamped position.
[0005] Considering the above points, there is a need in this industry for a better way to adjust the height of floating switches in pools or boxes. Summary of the Invention
[0006] In summary, this invention provides a new level of adjustability for all floating installation methods. Installers are now able to adjust the floating switch via the lead screw and rail design. The lead screw mechanism can be adjusted to position any type of switch at any location above the bottom or top of the tank or pool. For tethered floating switches, installers can still adjust the cable to achieve a greater swing amplitude when additional adjustments are needed, which will increase the total water level in the tank or pool, thus increasing the overall flexibility of the invention. For non-tethered switches, the switch can be installed according to this invention, and the lead screw will allow installers to adjust the floating position to multiple water levels within the tank or pool. After selecting the correct water level, the adjustment knob can be locked to prevent any creeping. All adjustments to the lead screw can be made outside the tank or pool without removing any covers, except to verify the desired water level. Specific Implementation
