Claim 5:
6. The belay device of claim 1, wherein the cam assembly includes the cam pivotably attached to the base plate with a spring, which assists the cam to rotate on the axis toward a braking position, but remains locked with the force of the magnets of the base plate and the cam assembly, wherein when a pulling force of the rope with the friction over the circumference of the cam overcomes the force of the magnets of the base plate and the cam assembly to separate allowing the cam assembly to turn whereby the wider part of the cam's circumference along with the spacer of the base plate presses the rope making the rope's travel along the gap between the cam and the spacer impossible, creating an automatic brake, at which point the added force of the spring on the axis of the cam assist in a controlled release of the rope as the lowering handle is pulled.
