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 customers
load upon request.

2. Breakdown voltage is measured in the presence of a radioactive ionising source. Switch leakage current is limited to
100 microamperes
