Electrical Ratings
Make-and-break Current Rating: 30 mA at 30
Vdc for 10,000 cycles of operation.
Carrying Current Rating: 100 mA at 50 Vdc
Contact Resistance: 50 mohms maximum
initially (measured at 10 mA, 50 mVdc).
150 mohms maximum after life.
Insulation Resistance:(measured at 100 Vdc
across open switch contacts)
Initial: 5000 Mohms minimum. After Life: 1000
Mohms minimum.
