1. THE METHOD OF CONDITIONING AN ALL-POSITION SEALED REED, MERCURY SWITCH BY STORING MERCURY ON THE CONTACTS AND THE SWINGER ONLY, THE COMPRISES INCLUDING A RESERVOIR IN THE TUBULATION THAT NORMALLY EXTENDS FROM THE SWITCH ENVELOPE DURING MANUFACTURE, INJECTING INTO THE ENVELOPE AN EXCESS OF MERCURY, EVACUATING AND SEALING THE TUBULATION AT A POINT TO INCLUDE THE RESERVOIR, ACTIVATING THE SWITCH BY AGITATING AND HEATING IT TO CAUSE MERCURY TO ADHERE TO THE CONTACTS AND THE SWINGER, TRANSFERRING THE REMAINING MERCURY TO THE RESERVOIR BY CENTRIFUGING AT A SPEED TO ATTAIN A RADIAL ACCELERATION 30 TO 35 TIMES THE ACCELERATION OF GRAVITY, SEALING THE TUBULATION BETWEEN THE ENVELOPE AND THE RESERVOIR, AND SEVERING THE TUBULATION TO REMOVE THE RESERVOIR.
