<p>An accelerometer (10) includes housing (16) retaining an actuator (28) movable between three positions partially disposed therein in the first position and an assembly including a first element (48) movable between three positions engaging and retaining the actuator (28) when in the first position, a second element (50) spaced from the actuator (28) and the first element (48) when each is in the first position to engage the first element (48) when the actuator moves from the first position to the second position when the acceleration greater than a first level is exerted on the accelerometer to close a first circuit, and a third element (52) spaced from the actuator (28) and the first and second elements (48 and 50) when each is in the first or second positions to engage the second element (50) when the actuator (28) moves from the first position to the third position when the acceleration greater than a second level is exerted on the accelerometer to close a second circuit.</p> |
