An inexpensive, enclosed pool mercury commutator suitable for use with small animals.
An electrical coupling device that utilizes small, enclosed mercury pools is described. This commutator is of small size, low torque, relatively noise-free, and controls possible mercury spillage. It is constructed of readily available, inexpensive materials, and requires no precision machining for assembly.
