Abstract
A neuromuscular stimulation device is described having a plastic casing housing a printed circuit board bearing control electronics, with the casing including an external integral flexible portion which is capable of being flexed into the interior of the casing so as to cause an electrically insulative substrate on which is carried an electrically conductive pathway to be pushed into contact with the PCB in order to complete an electrical circuit. Such a switch is relatively inexpensive to produce, as it has few moving parts, can be formed in a usual manufacturing process, and is robust.
Claims13
An electronic device comprising:
- a plastic casing defining an interior and exterior, the interior housing a printed circuit board having an electrical contact point, the casing incorporating an external integral flexible portion which is capable of being flexed into the interior of the casing;
- a flexible electrically insulative substrate on which is carried an electrically conductive pathway;
- a pair of electrodes that provide neuromuscular stimulation, located on the flexible electrically insulative substrate, the flexible electrically insulative substrate and the electrically conductive pathway extending out of the interior of the casing to the exterior of the casing to drive the electrodes, the electrodes being located outside the casing;
- wherein at least a portion of the flexible electrically insulative substrate is retained by the casing such that said portion is adjacent to but spaced from the printed circuit board;
- such that when the integral flexible portion is flexed into the interior of the casing, the integral flexible portion urges said portion of the flexible electrically insulative substrate into contact with the printed circuit board, such that the electrically conductive pathway contacts the electrical contact point, thereby completing an electrical circuit.
