What is claimed is: 1. A voltage block comprising first and second reservoirs, a switching device including an inlet port, an outlet port, a first reservoir port and a second reservoir port, the switching device mounted for movement between a first position and a second position in a third reservoir, the third reservoir including an electrically non-conductive fluid medium in which at least a portion of the switching device is immersed. 2. The voltage block of claim 1 including a first valve, a second valve, a third valve and fourth valve, the first, second, third and fourth valves immersed in the electrically non-conductive fluid medium. 3. The voltage block of claim 1 wherein the first and second reservoirs comprise piston-and-cylinder fluid motors. 4. The voltage block of claim 3 wherein the first and second reservoirs together comprise a double-acting, piston-and-cylinder fluid motor. 5. The voltage block of claim 1 wherein the third reservoir comprises a tank including a track to which the switching device is mounted for movement between the first and second positions. 6. The voltage block of claim 5 wherein, when the switching device is in the first position, the first valve couples the inlet port to the first reservoir port and the second valve couples the second reservoir port to the outlet port, and when the switching device is in the second position, the third valve couples the inlet port to the second reservoir port and the fourth valve couples the first reservoir port to the outlet port. 7. The voltage block of claim 1 wherein the third reservoir includes means for movably mounting the switching device, the voltage block further including means for moving the switching device between the first and second positions. 8. The voltage block of claim 1 further comprising molecular sieves in the third reservoir. 9. The voltage block of claim 8 wherein the molecular sieves are renewable. 10. In combination, a coating material source, a coating dispensing device, a high magnitude electrostatic potential source, a voltage block comprising first and second reservoirs, a switching device including an inlet port, an outlet port, a first reservoir port and a second reservoir port, the switching device mounted for movement between a first position and a second position in a third reservoir, the third reservoir including an electrically non-conductive fluid medium in which at least a portion of the switching device is immersed, a conduit for coupling the coating material source and the inlet port, a conduit for coupling the first reservoir and first reservoir port, a conduit coupling the second reservoir and second reservoir port, and a conduit coupling the outlet port and the coating dispensing device. 11. A method of coating an article comprising providing first and second reservoirs, providing a switching device, providing on the switching device an inlet port, an outlet port, a first reservoir port and a second reservoir port, providing a third reservoir including an electrically non-conductive fluid medium, mounting the switching device in the third reservoir for movement between a first position and a second position, and at least partially immersing the switching device in the electrically non-conductive fluid medium in the third reservoir. 12. The method of claim 11 wherein providing a switching device and providing a third reservoir together include providing first, second, third and fourth valves, and at least partially immersing the switching device in the electrically non-conductive fluid medium in the third reservoir includes immersing the first, second, third and fourth valves in the electrically non-conductive fluid medium. 13.
