Abstract
A rotary switch device such as that used on the probe end of an articulated arm coordinate measurement machine is provided. The rotary switch having a housing with an axis of rotation. A first actuator is coupled to the housing. A first switch is coupled to the first actuator, the first actuator being configured to selectively close the first switch. A first electrical circuit is provided. A first antenna circuit is electrically coupled the first switch to the first electrical circuit, wherein the first electrical circuit and first antenna circuit cooperate to modulate an operating field when the first switch is closed. A reader circuit is arranged fixed relative to the axis of rotation, the reader circuit including a transmitter configured to emit the operating field and a receiver configured to detect the modulated operating field.
