Resistance to electromagnetic interference : |
|
The switch operation cannot be totally eliminated from the effects of electro-magnetic interference.
It can affect switch circuit:
- through air and the resonance circuit coil,
- through the device structure and the switch case capacitive coupling,
- through the supply connection.
To avoid the electromagnetic interference, the switch circuit is provided with a filter which also affects the switching frequency of the switch. In general, resistance to electromagnetic interference is indirectly proportional to the switching frequency.
The switches of this catalogue are available as:
- basic models
- high-speed switches (the letter F follows the basic order reference number)
- low-speed switches (the letter S follows the basic order reference number)
