Abstract
A shock-responsive control apparatus has a seismic ball mounted in a seat formed in a cup-shaped member and surrounding the plunger of a switch. As the ball crosses a circular region, at which the inclination of the seat to the central axis of the apparatus increases, its path becomes more closely aligned with the resultant force acting on the apparatus and the ball is accelerated more rapidly out of obstructing engagement with the plunger. Sensitivity is controlled by moving the seat relative to the plunger by means of a screw-threaded mounted cover for the cup-shaped member.
