Shock and Vibration
If switches are likely to be subjected to shock or vibration, select models with the highest avail able actuating force. Saia-switches feature low mass mechanisms which are inherently resistant to shock and vibration. If possible, the switches should be mounted so that the line of acceleration is at right angles to the travel of the plunger. The maximum avail able overtravel should be used.
Direct Current
Direct current (DC) ratings where shown should not be exceeded if destructive arcing and contact welding are to be avoided. Some form of arc suppression is ecommended when switches are used in DC circuits containing inductive devices wired in series with the switch and the supply.
Lamp Loads
Because of the very high inrush currents associated with incandescent lamps, applications should be subject to individual assessment.
Capacitive Loads (including fluorescent lamps)
These can generate very high peak currents which can cause contact welding. Applications should be subject to individual assessment.
Inductive Loads
The general ratings tables included in this catalog provide data for switches used to control inductive circuits at a power factor of 0.5 (EN 0.6; UL 0,7 means HP-Rating 0,5).
