Electrical stimulation device and method for therapeutic treatment and pain management

An electrical stimulation device, comprising:

• a control module comprising a printed circuit board including electrical stimulation control circuitry;
• a housing enclosing the control module, the housing comprising
• an upper housing component and a lower cover, wherein the printed circuit board is positioned between the upper housing component and the lower cover, wherein a diameter of the upper housing component is larger than a diameter of the printed circuit board, and
• a rivet extending through the upper housing component, the printed circuit board, and the lower cover along a central axis, the rivet securing the upper housing component to the printed circuit board and the lower cover such that the upper housing component can rotate about the central axis of the rivet relative to the printed circuit board and the lower cover;
• an internal switch secured to an inner portion of the upper housing component, wherein the internal switch rotates with the upper housing component about the central axis relative to the printed circuit board;
• a plurality of contacts positioned on the circuit board;
• and
• a first connector disposed on the lower cover of the housing and configured to couple with a second connector of a first electrode to electrically couple the electrical stimulation control circuitry to the first electrode;
• wherein rotation of the upper housing component about the central axis is configured to cause contact between the internal switch and the plurality of contacts to provide control inputs for the electrical stimulation circuitry, wherein the control inputs comprise at least one of on, off, intensity adjust up, and intensity adjust down inputs.
