Abstract
An inertia switch including a cone-shaped inertia mass element movable from a stable condition wherein it supports a movable switch plunger in a position for maintaining a pair of switch blades in an open condition, into a collapsed condition in response to an impact bringing about an abrupt change in movement. In the collapsed condition the inertia mass will be out of its plunger supporting position allowing the same to activate the switch by permitting the switch blades to close.
