Abstract
Embodiments of the invention provide a float switch with a float housing having a magnetically-activated, hermetically-sealed reed switch secured within an interior cavity in a first orientation and a permanent magnet positioned in a second orientation. The permanent magnet is movable within a chamber in the interior cavity between a first activation position and a second non-activation position. For connection to a pump, electrical conductors extend from the float housing at one end and are electrically coupled to the reed switch.
Claims17
A float switch comprising:
- a float housing including an interior cavity and an exterior;
- a reed switch in a first orientation, the reed switch being magnetically activated and hermetically sealed, the reed switch being secured within the interior cavity;
- a permanent magnet in a second orientation, the permanent magnet being movable between a first activation position and a second non-activation position;
- the permanent magnet being positioned in and movable within a chamber, the chamber being within the interior cavity, the first activation position and the second non-activation position being within the chamber;
- and
- electrical conductors extending from the float housing, the electrical conductors electrically coupling to the reed switch to create an electrical circuit.
A float switch comprising:
- a float housing including an interior cavity and an exterior;
- a brace within the interior cavity;
- a reed switch in a first orientation, the reed switch being magnetically activated and hermetically sealed, the reed switch being secured by the brace within the interior cavity;
- a permanent magnet in a second orientation, the permanent magnet being movable between a first activation position and a second non-activation position;
- and
- the permanent magnet being positioned in and movable within a chamber, the chamber being secured by the brace, the permanent magnet being in the chamber in both the first activation position and the second non-activation position.
A method comprising:
- placing a magnetically activated hermetically sealed reed switch in a first orientation within an interior cavity of a float housing;
- placing a permanent magnet in a chamber, the chamber being within the interior cavity, the permanent magnet being in a second orientation, the permanent magnet being movable between a first activation position and a second non-activation position;
- sealing the chamber by placing a stop on at least one end of the chamber;
- and
- filling the interior cavity of the float housing with a filler material.
