Abstract
An apparatus includes a body assembly, a modular shaft assembly, and a coupling detection assembly. The body assembly includes a control circuit, a battery pack operable to power the control circuit, and a first electrical contact assembly. The modular shaft assembly includes a second electrical contact assembly that is configured to operatively engage the first electrical contact assembly when the modular shaft assembly selectively couples with the body assembly. A detection trigger member is configured to activate a detection activation member such that the detection activation member communicates a first detection signal to the control circuit when the modular shaft assembly selectively couples with the body assembly. The control circuit is configured to verify operative engagement between the first electrical contact and the second electrical contact in response to the control circuit receiving the first detection signal.
