22、his International Standard is applicable to variable capacitors, potentiometers and variable resistors for use in electronic equipment. The dimensions given in this standard have been selected from IEC 60390 and IEC 60620 because the ranges of dimensions included in these standards were considered t

23、oo large and contained too many variants for capacitors and resistors for electronic equipment. Consequently this standard contains preferred dimensions for shaft ends and bushes and for the mounting of single-hole, bush-mounted, shaft-operated variable capacitors, variable resistors and potentiomet

24、ers. If other dimensions not listed in this standard have to be used, it is recommended to select them also from the above-mentioned standards. 2 Normative references The following referenced documents are indispensable for the application of this document.
