Honeywell MICRO SWITCH does not recommend the use of silver cadmium oxide switch contacts in non-arcing loads. Non-arcing loads are generally loads less than 12 volts and/or 0.5 amp. Catalog listings in the 5, 6, 15, and 16HM Series use silver cadmium oxide contacts. If you have specific questions, contact the MICRO SWITCH Application Center at 1-800-537-6945. 2. For applications involving non-arcing loads, catalog listings in the 9,10,19 and 20HM Series are recommended. 3. The 1, 2, 5, and 6HM Series are recommended for use only in 3 to 4 amp range applications. 80 Honeywell Sensing and Control For application help: call 1-800-537-6945.
