1. The specification for VA rating may sometimes be exceeded for less sensitive (higher AT) switches, and should be
decreased for very sensitive (lower AT) switches. Standex-Meder Electronics will run life tests specific to a customer’s
load upon request.
2. Breakdown voltage is measured in the presence of a radioactive ionising source. Switch leakage current is limited to
100 microamperes
3.
Contact resistance measurements are made at 10ma from a 1-volt source, with 50% overdrive, using a 4-wire (Kelvin)
measuring system. Contact probes are located on 43 mm centres.
