APPLICATION PRECAUTIONS
1. Donotsubjecttheseswitchestotheinflu-
ence of strong magnetic fields.
2. When the magnet is exposed to ferrous
filings, a loss of sensitivity can be
expected.
3. Use arc suppression networks to extend
life in inductive circuits.
4. Do not subject these switches to extreme
vibration.
