1. An apparatus, comprising:
a slider of a magnetic recording head comprising a plurality of electrical bond pads coupled to bias sources and a ground pad;
a plurality of electrical components of the slider each coupled one or more of the electrical bond pads, wherein at least one of the electrical bond pads is a shared electrical bond pad coupled to at least a first electrical component and a second electrical component; and
a switching transistor coupled to the first and second components and the ground pad, the switching transistor arranged to control powering of the second component in response to biasing of the first component.
