摘要:
Ignition switch assembly suitable for being connected to a rotary shaft (2) of a gas tap (1) of a cooking appliance, comprising a coupling element (5) through which the ignition switch assembly (3) is coupled to the rotary shaft (2), said coupling element (5) being rotational and integral with the rotary shaft (2) in a rotational movement, a fixed contact means (20) and a movable contact means (25), and a cam (30) coupled to the coupling element (5), shifting the movable contact means (25) towards the fixed contact means (20), electrical contact being produced when the coupling element (5) is turned, wherein it comprises at least one resistance means (4), other than the cam (30), that resists against the rotational movement of the rotary shaft (2), making the force that a user must exert to turn said rotary shaft (2) greater.

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.

Disclosed is a rotary device that rotatably and movably supports a rotary body, thereby reducing the number of parts, as compared to the related art. A rotary body (and a code member that is supported such that it can be rotated together with the rotary body) is supported so as to be movable in an X1-X2 direction independently from a fixed base and a fixed board. A photo interrupter is fixed to the surface of the fixed base. The interrupter is arranged such that the direction of a straight line linking the center of a light emitting portion in the width direction and the center of a light receiving portion in the width direction is orthogonal to the direction in which the rotary body is moved, and when the rotary body is positioned at the center of the movement direction, the straight line passes through a rotation center.

The invention relates to a tap changer having a switching monitoring device, which is arranged above the upper transmission stage in a housing. For monitoring purposes, two cam switches are provided which are actuated by a cam disk which is connected to the contact-bearing switch column of the tap changer. The cam disk has a horizontally split contour at its end face, wherein one of the two cam switches runs on each partial contour.

The invention relates to a switchgear comprising an actuating shaft, an actuator, at least one circuit breaker and a housing. In prior art cam contactors, the precision cannot be increased as desired due to unavoidable tolerances, and a conflict between the demand for high precision and small installation dimensions frequently occurs. The aim of the invention is to further develop a switchgear of the aforementioned type whereby improving the switching precision and the resolution, that is, the reliable ability to differentiate between two different switching positions. To this end, a switchgear of the aforementioned type is further developed by the provision of at least one link serving as an actuator that, with a first link section, is connected to the actuating shaft, and, with a second link section, at least partially encircles the actuating shaft at a predetermined distance, whereby an actuating path for the circuit breaker(s) is provided on the convex side of the second link section by virtue of the fact that, at at least one predetermined position, the distance between the outer peripheral edge and the actuating shaft for a predetermined radian measure is greater that at other positions of the second link section.
