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.

Abstract:
This invention makes reference to interrupter high voltage air-insulated telescopic disconnection switch with moving contact for supplying pressure, consisting of: a first male conductor comprising a first guide-positioner means internally coupled with such first male conductor via an intermediate section, a plurality of double-sided contact plates peripherally coupled with the intermediate section border; a second female conductor coaxially separated from the first male conductor comprising a second guide-positioner means internally coupled with such second female conductor by an intermediate section; a plurality of double-sided contact plates peripherally coupled with the intermediate section border; a moving conductor consisting of guide means internally coupled with such moving conductor by an intermediate support, being such conductor mobile and coaxially coupled with the interior of the first male conductor, where it moves to an open position, and is separated from the first male conductor and to a close position where such moving conductor causes a contact between the first male conductor and the second female conductor, by interacting among themselves to the first guide-positioner means of the first male conductor, the second guide-positioner means of the second female conductor and the guide means of the moving conductor; a plurality of contact plates peripherally coupled with the intermediate support border of the moving conductor, each of such contact plates having contact means for supplying pressure.
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 (1) formed by a lower structural body (1a) and another, upper structural body (1b), which engage with one another in such a manner as to accommodate, within, flexible contact blades (L) and a rotary core (2), the structural bodies (1a, 1b) having contact surfaces (4a, 4b) provided with at least one projecting portion (5a, 5b); furthermore, an axially moveable commutator ring (3) is engaged on said rotary core (2).
