TERMINATION/FUNCTION 4. TERMINATION/FUNCTION Notes:
1 Standard Wire lead Length is 6 “ for other wire lead length, Use Wire length lead
Termination/Function code and Add “/” and the wire lead length required at the end of the part number. Example: HK255-73/10”
2 Hardware/Packaging Options may be added to the base part number by
adding a “/” with the option at the end of the part number. Example: HL251-73 / HDW ASSM Available options include:
2 Hex 2 Hex nuts (1 assembled on switch, 1 Supplied in bulk)
No Hardware No Hardware included HDW ASSM With Hardware assembled HDW bulk With Hardware bulk Poly With Polybag 3 The nbl toggle uses a black oxide plated metal bushing. NWN and NRD toggles uses a nickle plated metal bushing. NBL, NWH, and NRD toggles use a four pole base with pole 3 empty. 4 () indicates momentray function.
5 Maintained or Momentary action of the switch is determined by the combination
of the circuit and termination/function designation of the description. Example: HK25B-73 is a (ON)-OFF circuit with .250 TAB Terminals. 6 Screw terminals are supplied with screws assembled to terminals. 7 Nylon toggles are not available with momentary circuits.
8 The “O” circuit is a reversing circuit with jumpers from terminals 1 to 6, 3 to 4 and
Terminal 7 to 9.
9 A Specials “O” circuit is a reversing circuit called out with a “J” Following the
termination/function digit in the description. Jumpers are from terminal 1 to 5, 3 to 5, 4 to 9 and 6 to 7. 10 Special “O” circuit only available with .250 TAB terminals. Example: H0251J-73 Ordering Scheme
