Problems solved by technology

[0005] According to the existing electromagnetic relay with two a contacts, in its electric contact opening and closing mechanism, when the opening and closing time of one a contact and the other a contact are different, due to the difference in the opening and closing time The opening and closing action of the a contact is shifted to one side. As a result, the consumption of the a contact due to the arc is accelerated only on one side of the a contact and the other a contact, which cannot meet the requirements of commercialization. The question of expected electrical switch life

Abstract

The invention provides an electromagnetic relay capable of simultaneously verifying the contact of two a contacts. A contact component (45) remains on a contact piece holding element (27) installed at a movable paster (20), the contact component (45) has two mutually short-circuited contact pieces (28, 29) through a short-circuit part (30), a normal open movable contact (28A) is supported and fixed on a contact piece (28), an a contact is formed by a normal open movable contact (28A) and a normal open fixed contact (7A), another normal open movable contact (29A) is supported and fixed on another contact piece (29), another a contact is formed by another normal open movable contact (29A) and another normal open fixed contact (7B), and a signal fetching part (31) for adjusting the contact of two a contacts simultaneously is formed on the short-circuit part (30) in a protruding manner.

Description

technical field [0001] The present invention relates to an electromagnetic relay which is formed by driving a movable iron piece through the excitation or demagnetization of an electromagnetic coil mechanism and making an electric contact opening and closing mechanism with a movable terminal and a fixed terminal open and close. The electromagnetic relay of the mechanism of the contact simultaneity of two a contacts. Background technique [0002] In an electromagnetic relay that is switched mainly by a DC load, a structure in which contacts are arranged in series is adopted in order to reduce a contact voltage at the time of switching. [0003] In addition, in the electromagnetic relay that performs contact opening and closing of DC high voltage load, a movable iron piece is provided on the main body of the electrical appliance. The moving iron piece holds the sheet material, and the sheet material has three operating protrusions, and each operating protrusion is in contact ...
