<p>An electrical switch has a movable contact 15 and a fixed contact 14. A member 26 can move the contact 15 to make or break the switch. A latch including a movable device 16 controls the initial movement of member 26 but the member 26 then moves independently of the latch. The device 16 can be moved to release the latch either manually (by 31) or by another means. This other means can be an electromagnet 41; it also can be an inertia body 51 releasable from a rest position in response to excessive acceleration. <IMAGE></p> |
