摘要:
A high-stability miniature circuit breaker includes an operating mechanism, wherein a pivotal shaft of the operating mechanism fixed on a shell includes a first shaft section, a second shaft section and a shaft shoulder; the diameter of the second shaft section is larger than that of the first shaft section, and the diameter of the shaft shoulder is larger than that of the second shaft section. A lever is installed on the first shaft section through a first shaft hole in a pivoting way and used for limiting the axial position of a protruding mesa relative to the pivotal shaft through contact fit between the protruding mesa disposed on the lever and a thrust surface on the second shaft section. A latch assembly is installed on the second shaft section through a second shaft hole in a pivoting way; a first end face fitted with a support surface on the shaft shoulder is disposed at one end of the second shaft hole; and a second end face fitted with the protruding mesa is disposed at the other end of the second shaft hole. A first hasp fitted with a second hasp of the latch assembly is disposed on a connecting rod, the connecting rod is engaged with each other with the latch assembly in the first and second hasp contact and withhold state, and the latch assembly controls a drive rod and the lever not to move relatively; the connecting rod is separated from the latch assembly when the first and second hasps are separated and unbuckled, and the latch assembly is separated from the drive rod, so that the drive rod can slide along a groove of the lever.

摘要:
A key activation system for use in an electronic device, such as a handheld communication device is provided. The system comprises an activation mechanism associated with a key in the system, a first feedback system and a second feedback system. The activation mechanism is associated with the key activation system and provides a first feedback sense when the activation mechanism has triggered the first activation condition. The second feedback system provides a second feedback sense indicating when the key triggers the second activation condition. In the system, the second feedback system operates independently from the activation mechanism and the first activation condition is triggered before the second activation condition when the activation mechanism is initially engaged. An activation mechanism may be centrally located for a set of keys.

A keyboard for an electronic device, said keyboard comprising a front plate (2) and at least one key (1) extending through an aperture in the front plate (2), said key (1) having a shoulder (8) that is wider than the aperture in the front plate (2). The keyboard further comprising a dome foil (3) having a carrier part (11) and at least one collapsible dome (4) connected to the carrier part (11) by an elastically deformable portion that is more liable to deformation than the dome (4) itself when a pressure is applied to a top surface of the dome (4). The dome (4) is positioned underneath the key (1) that abuts the dome (4). When no external pressure is applied to the key (1), the dome foil (3) is arranged in such a relationship with the key (1), that the elastically deformable portion is elastically deformed, such that the key (1) is forced against the front plate (2) by the dome foil (3).

摘要:
In an electrostatic relay (31,101,111) in which a moving contact (56) and a movable electrode are displaced in parallel with a base substrate(32), an opening force is increased when the movable electrode is separated from a fixed electrode, and a structure is simplified to enhance a degree of freedom of design. A fixed contact portion (33) and a fixed electrode portion (35) are fixed to the base substrate (32). The fixed electrode portion (35) and a movable electrode portion (36) constitute an electrostatic actuator that displaces the movable electrode portion (36) and a moving contact portion (34). A movable spring (37a,37b) provided in a spring supporting portion (38,39) retains the movable electrode portion (36) in a displaceable manner. A cantilever secondary spring (84) is provided in the spring supporting portion (38), and a projection portion (85) is provided in a front end face of the movable electrode portion (36). The secondary spring (84) abuts on the projection portion (85) while being not deformed until abutting on the projection portion (85), before the moving contact (56) of the moving contact portion (34) abuts on the fixed contact (46a,46b) of the fixed contact portion (33) when the moving contact portion (34) and the movable electrode portion (36) are displaced.

Die Bedieneinheit für eine Fahrzeugkomponente, insbesondere für eine Heizungs- oder Klimaanlage eines Fahrzeuges, ist versehen mit einer Frontblende (10), mindestens einem Bedienelement (18), das um eine Kippachse (16) kippbar gelagert ist. Das Bedienelement (18) ist mittels eines nachgiebig gelagerten Zentrierelements (44) in eine Ausgangsstellung vorgespannt, aus der es durch Kippen um die Kippachse (16) in eine von zwei entgegengesetzte Richtungen in eine von zwei Betätigungsstellungen überführbar ist. An dem Bedienelement (18) ist eine Steuerfläche (42) ausgebildet, die beim Kippen des Bedienelements (18) mit verschwenkt und an der das Zentrierelement (44) anliegt. Das Zentrierelement (44) ist im wesentlichen quer zur Kippachse (16) und im wesentlichen senkrecht zu einer hinter der Frontblende (10) angeordneten Trägerplatte (54) vorgespannt und von einem eindrückbaren, rückstellfähigen Vorsprung (48) einer auf der Trägerplatte (54) angeordneten Elastomer-Matte (50) gegen die Steuerfläche (42) vorgespannt.
