Electrical Life:
100mA @ 5V DC
100mA @ 50V DC
80 milliohms maximum for all 4 contacts closed
30 milliohms maximum for 1 contact closed
1,000 megohms minimum @ 250V DC
250V AC minimum for 1 minute minimum
20,000 detent operations minimum
20,000 detent operations minimum
Note: A detent operation is one actuator position operation or stepping.
20,000 detent operations = 1,250 cycles for hexadecimal devices or
2,000 cycles for decimal devices. A cycle is one 360 ° rotation.

The DR series rotaries have not been tested for UL recognition or CSA certification.
These switches are designed for use in a low-voltage, low-current, logic-level circuit.
When used as intended in a logic-level circuit, the results do not produce hazardous energy.
