About stationary contacts in practice

  • Ragnar Holm


While the preceding chapters deal with the physics of stationary contacts seen from a theoretical aspect, this chapter gives examples of how to use the knowledge for understanding stationary contacts as they appear in practice. Here the word stationary expresses that switching at applied voltage appears either seldom or not at all and that therefore the wear, which occurs at switching on or off current by the contact, need not be considered. Typical examples of a stationary contact in the sense of this chapter are the terminal contacts of an ammeter and even the plug-socket contact.
