Series 25 has 12 and Series 28 has 16, and have similar contact diagrams with more positions. Series 21, 25, & 28 have alphabetical markings of terminals. Series 24 and 31 (both single and 4-hole mounts) have the numerical terminal markings as shown. Contacting variations that can be used with all Detent Switches are shown in the assemblage diagrams below.  The handle is shown in the 12 o’clock (0°) position. Either make- before-break (shorting) or break-before-make (non-shorting) contacts are available except as noted. STANDARD CONTACT ASSEMBLAGES AND DIAGRAMS OPTIONAL CONTACT ASSEMBLAGES AND DIAGRAMS (Consult Factory for More Details) Number 2 Two poles per section; double-break switching.   This assemblage is normally limited to three positions. Number 3 One pole per section; provides “OFF” and 7 tap positions. Number 11 Allows any one circuit to be opened while the rest are closed; make-before-break (shorting) only. This assemblage is not avail- able in Series 28. Number 1 One pole per section; double-break switching. Number 6 Cumulative tap switch; make-before-break (shorting) only. This assemblage is normally limited to four positions. Number 7 Provides double-break switching.  This assemblage is normally limited to four positions. Number 5 Three poles per section; double-break switching.  This assem- blage is available in, and shown for Series 25 only. Number 8 Allows pairs of circuits to be fed from a common source. Number 10 Same as Assemblage 3 except first position is “ON”.
