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:
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 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 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:
Die Erfindung betrifft eine mechanische Trennereinheit 1 zum Unterbrechen einer Leitung. Die Trennereinheit 1 umfasst dabei eine Kontaktanordnung und ein elektromagnetisches Antriebsmittel 5, 6. Die Kontaktanordnung weist einen ersten und einem zweiten Festkontakt 2, 3 sowie einen geführten Be- wegkontakt 4. Das elektromagnetische Antriebsmittel 5, 6 ist zum Bewegen des Bewegkontaktes 4 eingerichtet. Die Trennereinheit 1 kann einen ersten und einen zweiten Zustand einnehmen, wobei in dem ersten Zustand keine elektrische Verbindung zwischen dem ersten und dem zweiten Festkontakt 2, 3 besteht, und in dem zweiten Zustand der Bewegkontakt 4 die beiden Festkontakte 2, 3 elektrisch miteinander verbindet. Die Trennereinheit 1 ist durch Bewegung des Bewegkontaktes 4 vom zweiten in den ersten Zustand überführbar. Die Erfindung zeichnet sich dadurch aus, dass der zweite Festkontakt 3 eine Ausnehmung 31 zur Aufnahme des Bewegkontaktes 4 aufweist, und dass der Bewegkontakt 4 zumindest teilweise in die Ausnehmung 31 eingreift, wenn die Trennereinheit 1 sich im ersten Zustand befindet.
Abstract:
An elastomeric membrane switch having an elastomeric connector comprising a plurality of alternating vertically disposed conductive layers and non-conductive layers extending between upper and lower contact surfaces. The lower surface of the elastomeric connector is disposed over a substrate having electrically isolated, first and second contact pads of an electrical switch circuit. Each of the first and second contact pads is in electrical contact with different ones of the exposed ends of conductive layers of the lower contact surface. A resilient membrane having an electrically conductive interior surface is spaced a distance above the upper contact surface, whereby upon applying a downward force to the resilient member, the otherwise electrically isolated contact pads are electrically connected through the electrically conductive layers of the elastomeric connector and the electrically conductive interior surface of the resilient member.
