Abstract (en)
[origin: EP1914771A2] Disclosed is a closing spring assembly of a switching mechanism (1) for an air circuit breaker which is capable of being produced with low cost by a general pressing process, and of supporting a load caused by an elastic energy of the closing spring, comprising: a closing spring (3), a first spring seat member (7), a second spring seat plate (6), a spring guide pin (5) having both end portions connected to the first spring seat member (7) and the second spring seat plate (6), and installed to penetrate the closing spring so as to guide and support the closing spring, and a supporting bracket (4) for supporting the second spring seat plate (6) of the closing spring (3) to be rotatable within a limited angle.
