Abstract
A pivoted pointer or stylus is mounted for actuation by reciprocatory plunger action. It has a stop associated with the plunger to hold the stylus locked in a neutral position until the plunger is actuated. The stylus has a cam action surface for cooperating with another part of the stop after the stop has moved to release the stylus. The cam action causes pivotal movement of the stylus to indicate an event.
