Abstract
An inertia switch comprises a spiral spring-like member supported by a post in a housing, the spring comprising one contact of the switch and the housing the other. The post is insulated from the housing and provides a terminal for the switch. Acceleration or shock applied to the switch causes the spring-like member to move relative to the housing and when it contacts the housing or approaches a detector located inside and supported by the housing, switching is effected.
