Abstract
An electrical signal coupling device and more particularly, a rotary signal coupler suitable for use in transmitting electrical signals between transducers mounted on a shaft and wiring which is fixed relative to the structure in which the shaft is rotatably mounted. The coupling device includes a first part mounted on a rotary shaft and a second part mounted on the shaft in juxtaposition to the first part. The first and second parts include respective first and second conductors for electrically coupling the parts. The coupling device also includes means for maintaining a predetermined and substantially constant annular gap between the first and second parts and means, disposed on the second part, for preventing rotation of the second part as the first part rotates with the shaft.
