Abstract
The properties of materials for heavy-current contacts have been the subject of extensive research, but many of the tests developed over the years have fallen short of giving an accurate indication of how contacts will behave in service. Simple apparatus has recently been developed which can simulate the conditions actually experienced by contacts in switching devices; by separating the variables which determine contact performance, these tests may lead to the development of optimum contact materials for different applications.Keywords
