Profile: Inertia Switch Inc. is a full-service design, engineering, and manufacturing firm. We are an ISO 9001:2008 certified company. We specialize in acceleration switches of all kinds, but we also manufacture limit switches, prostheses, incandescent digital displays, and many other standardized & unique products. Our general purpose series covers an extensive range of commercial and military specifications. These units have been utilized in a variety of applications. This series is typically used when size is not the primary design constraint. Extra mass provides better electrical characteristics and allows rigid mounting, redundant contacts, micro connectors, adjustability & multi axis sensing. We offer a line of shock recorders and indicators for various commercial & military applications. These visual indicators are highly reliable, durable, and accurate, making them ideal for monitoring shipments or equipment where excess shock may have an adverse effect on the item being monitored. The PCB series inertia switches are intended for applications where size is a critical factor. Many commercial and military configurations exist. Damped and undamped models provide highly reliable performance throughout any dynamic environment. No power is required for operation making them an ideal choice for battery powered applications.
