摘要:
A cam rotary switch with double positive break contacts comprises a body including at least two components (1, 2) coupled with each other and enclosing fixed electrical contact elements (5, 6), one shaft (13) torsionally connected with a control member projecting from a first (1) of such components (1, 2), said shaft (13) having a widened extremal part (12) internal to the body of the switch and shaped in such a way as to selectively connect such fixed electrical contacts (5, 6) via the movement of movable contacts (7) internal to said body. Such fixed contacts (5, 6) co-operate with electrical connection members (33, 33K) projecting beyond the second component (2) of said body, said members (33, 33K) being suitable for being soldered on a board carrying a printed circuit (30).

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.

Electrically driven micro switch that is able to actuate galvanic connections between input and output rheophores (here below called "pins") by realizing a complete connection matrix. The small size micro switch allows to connect a largely definable number of pins and is particularly suited to telephony applications, by featuring for each input and output a double polarity, that can be associated to the poles of a telephone wire pair; the connections are mechanically realized so that they are maintained indefinitely without energy consumption and with a near zero connection attenuation. Furthermore, the micro switch is realized in order to allow the association between more than one micro switches to define an unlimited size connection matrix. The invention belongs to the technical area of electro mechanics and to the application area of electromechanical devices manufacture.

A rotary switch mechanism for an operation panel such that the space on a printed board is ensured, the design of electronic parts on the printed board can be readily made, and the attachability of a switch knob is good. Drive pieces are arranged at predetermined intervals around the end of a rotary knob behind the operation panel, and a detection switch for detecting the passage and the direction of the passage of the drive pieces is disposed in and near the extent where the drive pieces move.
