ABSTRACT:
An actuator responsive to seismic or other shock forces includes a first swinging arm yieldingly urged pivotally in one direction and releasably retained against such swinging movement by shock responsive means acting to permit swinging movement of the arm in response to predetermined shock forces, a second arm for actuating a controlled element and which is swung through an angle shorter than the first arm by a mechanical advantage linkage including two links pivotally connected together at first ends and pivotally connected at second ends to a support structure and to the mentioned second arm, together with a third link operable to swing the first and second links from relatively angularly disposed positions toward aligned and preferably overcenter positions in response to the swinging movement of the first arm to cause the desired relatively smaller movement of the second arm with resultant increased force applicable to the controlled element.
