Abstract
An earthquake actuated micro switch includes a ball which falls into a micro switch actuating position when disturbed. The ball normally resides in a shallow ball seat. A sufficient disturbance causes the ball to escape the ball seat, and fall into a switch seat. When the ball comes to rest in the switch seat, a lower surface of the ball pushes a micro switch actuator, thereby actuating the micro switch.
