13、99 2 Foreword This European Standard has been prepared by CENELEC Technical Committee 17X. Control switch contacts may be given a distinctive number and terminal marking in accordance with the General rules, EN 50005. On this basis, it is desirable to lay down more detailed rules for particular cont

14、rol switches, such as those defined in clause1. Contents Page Foreword 2 1 Scope 3 2 Terminal marking rule 3 3 Distinctive number 3 4 Terminal numbering sequence 3 Table 1 Diagrams of control switches 4EN50013:1977 BSI 10-1999 3 1 Scope This standard applies to control switches according to IEC Stan

15、dard 337-1, with two definite positions (such as push-buttons, limit-switches and similar devices), irrespective of their construction, having terminal marking in accordance with the corresponding marking of contactor relays designated by the distinctive letter E (seeEN50011). The use of this standa

16、rd is recommended where terminal marking is a requirement of the relevant standard for control switches, or is usual practice. 2 Terminal marking rule The contact terminal marking of a control switch is formed, in principle, by two figures. 2.1 Function number. The unit number is a function number,

17、i.e. 1 2 for break-contacts; 3 4 for make-contacts; 1 2 4 for change-over contacts. 2.2 Sequence number. The figure of the tens is a continuous sequence number beginning with 1 (except for control switches designated 01), independently of the contact function. The terminals belonging to the same con

18、tacts are marked with the same sequence number. The sequence number may be omitted from the terminal marking only if additional information provided by the manufacturer or the user clearly gives such number. NOTEThe dots before the function shown in the above examples are used merely to show the rel

19、ationship, and do not need to be used in practice. 3 Distinctive number The quantity and type of the contact elements of a control switch according to this standard are indicated by a distinctive number. In accordance withEN50005, clause 6, the first figure of the distinctive number gives the quanti

20、ty of make-contact elements the second one the quantity of break-contact elements. The third one, if any, gives the quantity of change-over contact elements in the control switch. 4 Terminal numbering sequence For control switches having the same distinctive number, the terminal marking is specified

21、 according toTable 1. The position of the contact elements on the control switch may not correspond to that shown on the diagram ofTable 1.EN50013:1977 4 BSI 10-1999 Table 1 Diagrams of control switches Distinc. number Contact elements Distinc. number Contact elements Distinc. number Contact element
