Abstract
A deceleration sensor switch comprises a base including a plate portion, a pedestal portion projecting from the plate portion, and a rod portion spaced from the plate portion and projecting from the pedestal portion. The plate, pedestal, and rod portions comprise a single continuous piece of plastic molded material. A mass is mounted on the rod portion and is movable relative to the rod portion between an unactuated position and an actuated position. The mass moves from the unactuated position to the actuated position when the mass is subjected to deceleration of a predetermined magnitude. A helical coil spring provides a restoring force which acts on the mass to move the mass relative to the rod portion from the actuated position back to the unactuated position after the mass has moved to the actuated position. An adjustable calibration screw is disposed at one end of the rod portion. The calibration screw is adjusted to adjust the restoring force of the helical coil spring acting on the mass.
