Abstract (en)

[origin: US2001054546A1] For increasing the reliability of contact closure in safety relays, a contact spring (10) is provided with two contact pieces (15, 16) which are disposed at the free end of the contact spring (10), spaced transversely of the longitudinal axis thereof and cooperate with contact pieces (17, 18) disposed on a common fixed contact. The contact spring (10) has a zone (19) in which it is not only flexible but also sufficiently torsional about its longitudinal axis in order to ensure the closure of both contact couples. Disposing the free end of the contact spring (10) carrying the contact pieces (15, 16) at an angle with respect to the fixed contact (12) achieves smooth and low-bounce contact closure and at the same time provides the function of a pre-contact and a main contact.
