  • Contact spring assembly
    Publication number: 20070012478
    Abstract: The present invention relates to a method of securing a reliable electrical contact between two adjacent surfaces by means of a contact spring (30) of a contact spring assembly (1). The secure and reliable contact is achieved by providing excellent conditions for maintaining the contact spring fully operable at all times and is accomplished by providing a shelter (12) for the contact spring (30) on a carrier (10) therefore, thereby protecting the contact spring by eliminating the possibility of the contact spring being overloaded and plastically deformed during installation.
