Abstract
A lead comprises a mechanical switch at a proximal end of a rotatable shaft. The mechanical switch has a first position to electrically connect a first electric conductor to a second electric conductor for electrically activating a pin and has a second position to electrically connect the first electric conductor to the rotatable shaft for electrically activating a helix. Proper fixation of the helix to an organ is determined by inserting a stylet into the mechanical switch to render the pin electrically active and the helix electrically inactive. Upon determination of proper fixation of the helix to the organ, the stylet is removed from the mechanical switch to render the helix electrically active and the pin electrically inactive.
