An arc fault circuit breaker includes a panel having a first side and an opposite second side, a housing coupled to the opposite second side of the panel, separable contacts, an operating mechanism structured to open and close the separable contacts, and a trip mechanism cooperating with the operating mechanism to trip open the separable contacts. The trip mechanism includes a test circuit structured to simulate a trip condition to trip open the separable contacts, and a proximity sensor disposed on or within the housing proximate the opposite second side of the panel. The proximity sensor is structured to sense a target to actuate the test circuit when the target is disposed proximate the first side of the panel and opposite the proximity sensor.
102 Thermal switch with self-test feature US10907086 2005-03-18 US07358740B2 2008-04-15 George D. Davis; Byron G. Scott
A normally open thermal switch (200) having a bimetallic disk (18) is configured for operational testing in its installed position when exposed to a changing temperature by a test box (400) having a power source (400a). The in-place testing advantageously confirms triggering action of the switch by an event indicator (400c) at the operational temperatures designed into the switch (200). The temperature of the triggering action is presented on a temperature display (400b) and recorded by a data recorder (400d) of the test box (400). The switch (200) incorporates a heating element (24c) to heat changing the bimetallic disk (18) to snap activate at the operative temperatures. The thermal switch (200) is coupled with the test box (400) to confirm its operation without having to remove the switch from its installed location.

116 Impact sensor for vehicle safety restraint system US142045 1993-10-28 US5485041A 1996-01-16 Jack B. Meister
An acceleration sensor that includes a permanent magnet mounted for movement within a cylindrical cavity in a body of non-magnetic material. The magnet has a cylindrical geometry and an outer surface with a first portion of electrically conductive construction entirely around the magnet adjacent to one axial end thereof, and a second portion of electrically non-conductive construction entirely around the magnet adjacent to an opposing end thereof. A pair of diametrically opposed electrical contact leaves extend through openings into resilient sliding contact with the magnet. The magnet is resiliently urged toward one end of the cavity such that the contacts are in engagement with one of the first and second surface portions. Acceleration forces on the magnet move the magnet toward the opposing end of the cavity, bringing the contacts into engagement with the other of the first and second surface portions, such that motion of the magnet within the cavity results in a change in electrical conductance between the contacts.
