<p>Various improvements are disclosed for an inertia switch device comprising an inertia body (12), a casing (11) forming a compartment for the inertia body and providing a rest position therefor, and a toggle (15) operable by the inertia body when it is disturbed from its rest position from a first to a second toggle position, a member (19) mounted in the casing operable for moving the toggle from its second to its first position. The member may be biased to a rest position in the casing which is independent of the toggle position. There may be three contacts (21-23) the first of which is electrically connected only to the second when the toggle is in its first position and only to the third when the toggle is in its second position. The casing may have a longitudinal axis, being formed in one or more pieces, each of which encircles said axis. The casing may be formed with sideways extending mounting lugs, one on either side of the casing, the lugs being formed with fixing holes, the adaptor being provided with a slot for receiving said lugs from above, the adaptor being formed with fixing holes which extend above the position of the lugs when received in said slot, the spacing of the closest parts of the adaptor fixing holes being less than the distance between the ends of the lugs, the arrangement being such that when fixing members extend through the adaptor holes, they lock the lugs in position in the adaptor slot. A member may be mounted in the casing operable for moving the toggle from its second to its first position and a flexible cap mounted on the casing covering the member, the member being operable by pressure applied to the cap.</p> |
