Manual actuator for regulating of switching hand held power tool

摘要

A manually operated hand held apparatus adapted to start up and effect switching processes that are actuated in response to manual pressure applied by the finger of an operator to a movable member, said apparatus comprising: a displaceable element which may be shifted by manual pressure applied by the finger of an operator for controlling the apparatus, said displaceable element having a portion in contact with said movable member that causes actuation of said apparatus when said displaceable element is shifted from a home position into an operative position, and a front contact portion comprising a recess and an elastomeric surface secured in said recess and positioned to be contacted by at least a finger of the operator when manual pressure is exerted on said displaceable element by the finger of the operator to shift said displaceable element into said operative position to control operation of said apparatus, said elastomeric surface providing a resilient cushion for the finger of the operator during application of pressure by the finger of the operator on the front contact portion to shift said displaceable element into said operative position
