Contact plating (finish) provides corrosion protection for base metals and optimizes the mechanical and electrical properties of the contact interfaces.

The DC Voltage ratings are the AC voltage values times 1.41 (usually rounded).

Current rating is the maximum current that a fuse will carry for an indefinite period without too much deterioration of the fuse element.

This function will evaluate a given expression (or a value) against a list of values and will return a result corresponding to the first matching value. In case there is no matching value, an optional default value will be returned.

The different types of lamps include:Incandescent Lamps,Tungsten Halogen Lamps,Fluorescent Lamps,Compact Fluorescent Lamps,Mercury Vapour Lamps,Metal Halide Lamps,High Pressure Sodium Vapour Lamps,Low Pressure Sodium Vapour Lamps.

IP (or "Ingress Protection") ratings are defined in international standard EN 6529 (British BS EN 6529:1992, European IEC 659:1989). They are?used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies?(tools, dirt etc) and moisture.
