Abstract
A step-by-step electric relay structure of a bistable type, comprising a mechanical part and an electric part, the mechanical part comprising push-button means to be operated by a user and the electric part comprising coil means, capacitor means, resistor means and diode means operatively interconnected to one another, the coil means comprising either two coils coupled in parallel to one another or a single coil polarized or biased with two polarities, thereby, as the push-button means are operated by the user to provide a switching or exchanging of at least a contact of the relay structure, either one of the two coils is shorted or the two polarities of the single coil are mutually reversed, thereby providing the electric relay structure with a logic SET function and a logic RESET function.

A step-by-step electric relay structure of a bistable type, comprising a mechanical part and an electric part, said mechanical part comprising push-button means (P.P.) to be operated by a user and said electric part comprising coil means, capacitor means (C1, C2, C3), resistor means (R1-R4) and diode means (R-S) operatively interconnected to one another, characterized in that said coil means (A or B) comprise two coils (A and B) coupled to one another, thereby, as said push-button means are operated by said user to provide a switching or exchanging of at least a contact of said relay structure, said capacitors (C1, C2, C3 or C1 through R1-R3) are charged, and one (A or B) of said two coils (A and B) is shorted, thereby providing said electric relay structure with a logic SET function and a logic RESET function.
A step-by-step electric relay structure of a bistable type, comprising a mechanical part and an electric part, said mechanical part comprising push-button means (P.P.) to be operated by a user and said electric part comprising coil means, capacitor means (C1, C3), resistor means (R1-R4) and diode means (R-S) operatively interconnected to one another, characterized in that said coil means (A or B) comprise a single coil (A or B) polarized or biased with two polarities, thereby, as said push-button means are operated by said user to provide a switching or exchanging of at least a contact of said relay structure, said capacitors (C1, C3 or C1 through R1-R3) are charged, and said two polarities of said single coil (A or B) are mutually reversed, thereby providing said electric relay structure with a logic SET function and a logic RESET function, said capacitors comprising a first capacitor (C3) connected in parallel to said single polararized or biased coil (A, B), opposite ends of said first capacitor (C3) being connected to respective first and second positions (R,S) of an exchange contact, said resistors comprising a pair of resistors (R4, R5) connected between said opposite ends of said first capacitor (C3) and a terminal (C) of said exchange contact.
