  • Mechanical held by leaf spring and contact pressure is kept constant, therefore no change in contact conductivity due to voltage fluctuations.
  • No operating current required after the transfer because of the mechanical hold mechanism.
  • Contacts are made from silver alloy for high resistance to burn-off.
  • Contact is always reliable thanks to the sliding design that clears contact’s dust and oxidization.
  • Manual operation handle able to provide manual change-over and neutral locking.
