An acceleration switch that operates even when acceleration is applied to the acceleration switch from a direction other than a predetermined detection direction. The acceleration switch (1) includes a movable portion (M1), which has a movable electrode (12), and a fixed electrode (14). The movable portion includes an inertial weight (8) moved in accordance with the application of acceleration, a beam portion (10) for pivotably supporting the inertial weight, and a plurality flexible plates (11) that are arranged in the inertial weight and each have a distal end in which the movable electrode is located and are flexed separately from one another. The flexible plates separately move to contact the fixed portion when acceleration is applied from a direction other than a predetermined direction. |

Der Schalter hat einen auf Beschleunigung ansprechend auslenkbaren Massekörper (16), durch den ein Schaltsystem (24) betätigbar ist. Um mit nur wenigen einfachen Bauteilen eine zuverlässige, gut reproduzierbare Schaltfunktion ohne jegliche Justierung zu gewährleisten, ist der Massekörper (16) an zwei parallelen, elastisch auslenkbaren Lagerarmen (12, 14) aufgehängt, die ein erstes, fest verankertes Ende und ein zweites, bewegliches Ende haben, an dem der Massekörper (16) befestigt ist. |

Die Erfindung betrifft einen Beschleunigungsgrenzwertschalter mit einem kugelförmigen Trägheitskörper, der von einem Dauermagneten in einer Ruhestellung gehalten wird. Über dem Trägheitskörper ist eine leitfähige Membran befestigt, der eine Leiterplatte gegenüber steht. Bekannt ist es, den Trägheitskörper in einem trichterförmigen Raum zu lagern. Da dieser rotationssymmetrisch ist, gibt es keine bevorzugte Ansprechrichtung. Da für bestimmte Anwendungsfälle eine richtungsabhängige Auslösung gefordert wird, liegt der Erfindung die Aufgabe zugrunde, einen derartigen Schalter mit Vorzugsrichtung zu schaffen. Erfindungsgemäß wird der Bewegungsraum des Trägheitskörpers so umgestaltet, dass er nur in einer Richtung zur kontaktgebenden Membran rollen kann. |

A micromechanical acceleration switch of silicon or similar materials, comprising a resilient electrode element, a proof mass, a housing and a spring element connecting the electrode element and the proof mass to the housing. The electrode element is mechanically connected adjacent to the proof mass. The proof mass has its centre of gravity located at a given distance from the axis through the spring element, so that when the proof mass is pivoting about the axis of the spring element in response to an externally applied acceleration, with a component in a direction parallel with the first axis. The electrode element also pivots about this axis. The pivot angle being essentially proportional to the magnitude of this component of the acceleration. The resilient electrode element has a mass considerably smaller than the proof mass, and is provided with at least one electrical contact point giving electrical contact and co-operation with corresponding contact areas in said switch housing at a given pivot angle of the electrode element. |

By providing a semiconductor accelerometer switch having a fixed portion (2) including a first control electrode (6) and a movable portion (3) including a movable body (30) and by applying an electric voltage between the first control electrode (6) and an electrode (11) formed in the movable body (30), an electrostatic attraction is exerted on the movable body (30) to hold it in an initial position. The movable body (30) is displaced when an acceleration having a predetermined magnitude in a predetermined direction is effected on the switch. Hence, it is possible to solve problems of conventional devices where labour time is increased when changing a design depending on a threshold value of an acceleration to be detected and where general-purpose properties of the accelerometer switch are limited. |

A protecting device has a disconnecting contact (13) connected to the load current line (2) and actuated by an electromagnetic system (9). A shunt circuit leads from the side of the disconnecting contact (13) opposite to the battery to an earth line (3), via a diode polarised in the blocking direction. The earth line (3) crosses or extends through the ferromagnetic circuit of the electromagnetic system (9). When the battery terminals are connected to reverse poles, a high short-circuit current flows through the diode (23) and induces an excitation in the ferromagnetic circuit (11, 12) of the magnetic system (9), lifting the armature (12) and opening the disconnecting contact (13). | ||||||

An automotive inertia switch (1) including a switch body (10) which houses a movable plunger weight (11); a button guide structure (12) with a cylindrical nest (13), a switch reset button (14), a wiper contact (15) and a compression spring (16). Switching action is caused by the vertical movement of the weight (11). In an untripped state a tip (40) of the weight (11) is spring biased by the compression spring (16) into the nest (13). In response to a rapid change in the acceleration of the vehicle, e.g. a crash, the tip (40) is dislodged from the nest (13) and the weight (11) is forced by the spring (16) to move upwardly against the button (14). Vertical movement of the weight (11) causes the wiper contact (15), which is in pressing engagement with the opposite end of the weight (11), to move between switching positions to make and break electrical connection of a common terminal (6) to the fuel pump (2) or a switch status indicator. The tripped status of the switch (1) may be indicated by the switch status indicator, or by visual observation of the outward projection of the button (14). The switch (1) may be reset by simply pushing the button (14) downward to force the tip (40) back into the nest (13). |

An accelerometer (10) features a housing (12) having a passage (14) of rectangular cross section formed therein, the width dimension of which gradually increases with increasing displacement along a central longitudinal axis (16) away from a first end (24) of the passage; and a puck-shaped magnetic sensing mass (26) located within the passage whose magnetic axis extends in a direction normal to the basal surface (18) of the passage. A pair of magnetically-permeable elements (22) on the housing magnetically interact with the sensing mass so as to bias the sensing mass towards a first position within the passage; and a first and second pair of stationary beam contacts (30) project into the passage so as to be bridged by respective electrically-conductive circumferential surfaces (28) on the sensing mass when it moves to a second position within the passage. A pair of electrically-conductive nonmagnetic plates (32) on the housing magnetically interact with the sensing mass to damp the movement thereof within the passage. A pair of horizontally-wound coils (36, 38) provide both test and reconfiguration functions. | ||||||

A micromechanical memory sensor includes a latch member assembly (20, 30) mechanically latching upon detection of a threshold value of a variable condition (ambient temperature, acceleration, pressure). The mechanical latching is detected by circuitry of a readout mechanism (21, 22). The sensor further includes a resetting mechanism such as a thermal resistor (24), proof mass (52, 101) or electrostatic combing drive (170, 175) for electrically unlatching the latch member assembly whereby the sensor is latched purely mechanically in its operative states and is electrically reset for repeat use. | ||||||

An improved acceleration sensor (10) includes a housing (12) having an internal passage (14) defined therein, a sensing mass (18) located within the passage which moves from a first position within the passage towards a second position therein in response to acceleration inputs to the sensor housing, and a pair of electrical contacts (22) projecting into the passage so as to be bridged by the sensing mass when it reaches its second position within the passage, thereby closing an electrical circuit. The supported end (28) of each of the contacts includes diametrical arms (32) which are themselves secured to the housing only at their outboard ends (36). The arms are thus free to rotate elastically when the sensing mass deflects the contact's cantilevered free end (30), thereby permitting greater elastic travel of the contact's free end, with its enhanced reliability and an attendant increase in contact dwell. |
