Abstract:
1. An apparatus, comprising: a vacuum pump motor; a housing configured to be coupled to the vacuum pump motor having an adjustable bracket connected thereto; a diaphragm sealingly coupled to the housing, the diaphragm configured to move when the vacuum pump motor is actuated in a manner to apply a negative pressure to the housing; a magnet coupled to the diaphragm; and a magnetic reed switch connected to said bracket at a critical set-point and operatively coupled to the magnet, the magnetic switch configured to be actuated by the magnet when the magnet is a threshold distance from the magnetic switch such that said magnetic switch selectively actuates the vacuum pump motor and whereby said diaphragm increases in concavity as pressure in said housing increases and said magnet moves farther away from said magnetic reed switch and at said critical set-point, said magnetic reed switch switch opens causing the vacuum pump motor to turn off and pressure leaks from said housing.
