NOTE:   The data shown above are initial values.
  1. The contact resistance is possible with 1 A applied at 5 VDC using a fall-of-potential method.
  2. Testing conditions: The insulation resistance was measured with a 500 VDC megohmmeter at the same locations as the dielectric strength was measured.
  3. This value was measured at a switching frequency of 120 operations/min.
Note:1. All units are in millimeters unless otherwise indicated.
