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).

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.

In order to optimize the production of electrical switching contacts, particularly for vacuum tubes, a Field Assisted Sintering Technology process is proposed in which an electrical or electromagnetic field supports and/or produces a sintering process for producing semifinished contact elements for electrical switching contacts, contact elements for electrical switching contacts and/or electrical switching contacts, particularly for vacuum tubes. According to an embodiment, the contact material prior to the sintering process is present in such a form that the material composition of the contact material and/or at least one property of the contact material varies in at least one body direction of the finished contact element.

A method for patterning an amorphous alloy is provided. The method includes forming a pattern for defining an amorphous alloy deposition region on a parent material, forming an amorphous alloy deposition layer on the parent material with the pattern formed thereon, and etching a region except for the amorphous alloy deposition region. A dome switch is provided. The dome switch includes a metal layer shaped like a dome, a central portion of which protrudes, and, in response to external force being received through the protruding central portion, the central portion contacting and electrically connected to a circuit board, and an amorphous alloy layer disposed on the metal layer. Accordingly, an amorphous alloy structure with enhanced durability and reliability is easily manufactured.

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.

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.
