1. A bat swing training device comprising:
a base assembly having an outer base with a generally circular shape and an open top with a receiver ring having a first plurality of flanges extending inwardly from the open top and an inner ring having a second plurality of flanges that align with and connect to the first plurality of flanges;
the inner base having a pump housing, a neck with an opening that extends from a top of the neck into the pump housing, a plurality of ribs extending outwardly from the neck in a radial arrangement along an interior surface of the inner base, and a durometer of approximately 85A;
the outer base having a battery housing, a switch opening and a switch assembly mounted to an interior surface positioned within the switch opening such that a switch plate of the switch assembly is at least partially positioned outside an exterior surface of the outer base, and a material harder than the inner base;
the switch assembly has a first set of springs and second set of springs connected to the switch plate and wherein the first set of springs have a length that is less of the second set of springs such that wherein when the switch plate is pressed the switch plate compresses in an arc;
the base assembly connected to an arm assembly having a middle tube and an upper tube that are connected by a tube splice member and a first shallow fastener received through the middle tube and the tube splice member without the first shallow fastener entering into a central bore of the tube splice member and a second shallow fastener received through the upper tube and the tube splice member without the second shallow fastener entering into a central bore of the tube splice member;
the middle tube having a relief formed in a top end of the middle tube and a clamp received over the top end, wherein the relief is configured to prevent the middle from deforming when the clamp is clamped on the middle tube;
a suction assembly connected to the base assembly and the arm assembly; and
the suction assembly connected to a pump and a push union fitting connecting a coil hose and an upper hose, and a nozzle assembly connected to the upper hose and having a nozzle with a durometer between 55A and 65A and a length of approximately 158 mm;
the coil hose having a length of 620 mm a first elongated portion, a coiled portion having exactly coils and positioned 445 mm above the connection of the coiled portion to the pump and a second elongated portion; and
the nozzle having a suction cup with a diameter that covers between 3% to 5% of a regulation baseball wherein when in contact with the regulation baseball;
wherein the suction assembly is configured to hold a ball in a stationary position.
