Abstract:
A contact device includes: a contact block including a plurality of fixed terminals on which fixed contacts are formed, and a movable contactor on which movable contacts contacting and leaving the fixed contacts are formed; and a driving block that drives the movable contactor. Moreover, it is made possible to extinguish arcs, which are generated in an event where the contacts contact and leave each other, by arranging permanent magnets on a periphery of the contact block. Then, at least one fixed terminal among the plurality of fixed terminals is formed so that the fixed contact and the movable contact can abut against each other in a region other than a side opposite to the other fixed terminal.
Abstract:
A modular transfer switch (22) and actuator (20) wherein multiple transfer switches are connectable in linear arrangement with the actuator such that the actuator controls the position of all of the transfer switches. Each of the transfer switches (22) includes a contact assembly (48) that converts over-rotation of the drive linkage (26) in the transfer switch to added pressure between the load contacts and the power contacts in the contact assembly.
Abstract:
A relay (1) includes a motor (20) and a primary electrical switch assembly (132). Primary electrical switching attachment points (113) are switched by a moveable switching link (101) which is moved in and out of the switch on an switched off position axially by the motor (20) in response to electrical signals delivered to the coil (26) via the flexible leads (32, 33). The switching link (101) includes a mercury reservoir (119). A piezoelectric disk bender (105) displaces mercury to close the gaps between the attachment points (113).
Abstract:
The present invention discloses a de-bouncing keypad and a preparation method thereof, wherein the keypad is composed of a rubber substrate and a metal contact having three layers of layered structures. A layer of tin alloy or lead alloy is plated on a surface of the metal contact by electroplating or chemical plating. The metal contact plated with the tin alloy or lead alloy has excellent contact bouncing resistance and arc-ablation resistance, and the metal contact is further composited with the rubber to shape and prepare the rubber de-bouncing keypad.
Abstract:
A mechanical circuit breaker unit for interrupting a line includes a contact arrangement and an electromagnetic drive. The contact arrangement has first and second fixed contacts and a guided moving contact. The electromagnetic drive moves the moving contact. The separating unit can assume a first state and a second state. No electric connection exists between the first and second fixed contacts in the first state. The moving contact electrically connects the two fixed contacts to each other in the second state. The separating unit can be transferred from the second state into the first state by moving the moving contact. The second fixed contact has a recess for receiving the moving contact, and the moving contact engages at least partly into the recess when the separating unit is in the first state.
Abstract:
A switch includes a first arm that is rotatably supported, a first contact member that is provided at a free end of the first arm, a second arm that is rotatably supported, and a second contact member that is provided at a free end of the second arm and is to come into contact with the first contact member. After the first contact member and the second contact member have come into contact with each other, a point of contact between the first contact member and the second contact member is displaced with rotational motions of the first arm and the second arm.
Abstract:
The present invention relates to a switch device for ignition systems and, more particularly, for use in cooking equipment or heating systems in general, such as to obtain the electrical contact necessary to generate the spark for activating the burner. More preferably, the present invention includes innovative functional and technical aspects capable of promoting the electrical contact necessary to activate the burner, but principally to increase the levels of safety in relation to movement of the controls of cooking equipment/heating equipment, principally in connection with the return movement of said control. Therefore, the present switch device comprises a casing formed by a lower structural body and another, upper structural body, which engage with one another in such a manner as to accommodate, within, flexible contact blades and a rotary core, the structural bodies having contact surfaces provided with at least one projecting portion; furthermore, an axially moveable commutator ring is engaged on said rotary core.
Abstract:
A contact device (10) includes: a contact block (3) including a plurality of fixed terminals (33) on which fixed contacts (32) are formed, and a movable contactor (35) on which movable contacts (34) contacting and leaving the fixed contacts (32) are formed; and a driving block (2) that drives the movable contactor (35). Moreover, it is made possible to extinguish arcs, which are generated in an event where the contacts contact and leave each other, by arranging permanent magnets (46) on a periphery of the contact block (3). Then, at least one fixed terminal (33) among the plurality of fixed terminals (33) is formed so that the fixed contact (32) and the movable contact (34) can abut against each other in a region other than a side opposite to the other fixed terminal (33).
Abstract:
Eine elektrische Schalteinrichtung hat auf einer Leiterplatte (1) eine elastische Schaltmatte (4) mit einem hutartigen, von der Leiterplatte (1) abgehobenen Schaltbereich (5), der an seiner inneren Stirnfläche (7) eine elektrisch leitende, bei Druck auf den Schaltbereich (5) gegen Leiterbahnen (2, 3) der Leiterplatte (1) bewegliche Schaltbrücke (8) hat. Diese Schaltbrücke (8) ist durch ein von der inneren Stirnfläche (7) gehaltenes Metallplättchen gebildet.
