2) Storage Temperature. Long term exposure at elevated temperature may degrade solderability of the leads.
3) Operate (including bounce) /Release Time. Tested per EIA/NARM RS421A with diode suppressed coil.
4) Rating Sensitivity. The value at which the contact ratings and operating characteristics are determined. De-rating may be required below this value.
1) Contact Rating. Product of the switching voltage and current must never exceed the wattage rating. Contact Hamlin for additional load/life information.
