Switch device for an ignition system

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.
