Compliance is checked by Inspection and by manual test.
NOTE 1 If any change of the setting occurs, it should be possible to restore the selling by operation of the eonlrol s. Circuits and contacts which are not Intended for external loads are operated with the designated load. The Intended mfithodfs of mountitiy and the Intended oriGnla!

NOTE 2 Switches submitted in an appliarce may be tested using the circuit in tlie appliance and classified according to 7 1 2 5 as a declared specrfic load. Compliance is checked by the following tesi, which is ic out with uninsulated copper conductors, at first having ic largest cross-sectional area, and then having the smallest cross- sectional area specified in table 4: The circuit is calibrated with the following tolerances: Compliance is ctiecked by measurement.
The shape of the btada of the test screwdriver must suit the head of the screw to be tested. Traces of rust on sharp edges and any yellowish film removable by rubbing are ignored. You may delete a document from your Alert Profile at any time. Symbol elements, qualifying symbols and other symbols having general application lEC The declared full travel of the actuating member if any shall be applied during these tests.
Sealing compound whfch softens in heat provtdes satisfactory locking only.
BS EN IEC – Switches for appliances. General requirements
The overcurrent relay shalf ic trip when the output current is less han tOO niA. 610581 thickness of the specimerj shall not be less than 2,5 mm: For switches where the marking of the switch position is impossible or leads to misunderstanding, for example rocker switches or push-button switches with more than one biased push-button, the direction of actuation s shall be marked.
NOTE 3 For switches used in tropical climates, additional requirements may, be necessary.
If there are more “ON” positions, then the verification shall be realized at the most unfavourable one. Cartridge, fuse- links tF.
Switches for appliances – Part 1: General requirements
The 610581 of the circuit in which the switch is tested Is shown in figure If a decorative cover is backed by an inner cover, fracture of the decorative cover is neglected if the inner cover withstands the test after removal of the decorative cover If a switch is normally provided without an actuating member, then a suitable actuating member should be supplied by the manufacturer for the purpose of this test.
For all switches except electronic switches the test current may be reduced to f-R by introducing a resistor in the circuit.
The conventional fusing currents to be used for these tests are specified in table 26, Table 26 – Conventional fusing current versus rated current Device Rated current A Conventional fusing currenl’l A Cord switches Up to and including 16 26 Indepondont’y mounted switches Up to and including 16 26 Over 16 up to nnd inrliidmg 3? Compliance is checked by inspection.
Width X Pollution degree Minimum values 1 0,25 mm 2 1,0mm 3 1,5 mm If the associated clearance is less than 3 mm, the minimum width X may be reduced to one- third of this clearance The methods of measuring 61085-1 distances and clearances are indicated in the following examples 1 to During the measurements, 6108-1 one of the resistors and all other components, if any.
Particular requirements for cord switches Switches for appliances — Part Where this is not practical on the specimens to be used for the test of clauses 16 and 17, the test of Be the first to review this item Would you like to tell us about a lower price? Therefore; the circuit ie the load side is always considered to be live. The switching frequency of the cut-out may be increased above the normal switching.
After the tests the electronic switch shall be m ttie original state and the setting shall be unchanged.
