accessories to fit any 12V or 24V application.

The Snap-In concept of both the switches and panel mount bezels allow for quick and easy installation.

1 Appendix A-1 Appendix A MODULAR SWITCH SYSTEM Items Shown: A - Flush Mount Switch B - Connector Plug C - Indicator Light D - Indicator Bezel Insert E - Blank Plug F - 4-Gang Switch Bezel The Euramtec Modular Switch System has the flexibility to allow for the mixing and matching of switches and accessories to fit any 12V or 24V application. The NP heavy duty switches were designed and manufactured to meet the highest standards of durability and reliability required by OEM manufacturers. The Snap-In concept of both the switches and panel mount bezels allow for quick and easy installation. Lenses for the switches are available in several colors. The graphics can be either selected from the library of pre-existing symbols or custom made to suit the desired function. Mating connector plugs and terminals are also available as accessories to the modular system U.S.A.

2 Appendix A-2 How to Use The Modular Switch System Bezels: The flush mount switches require the use of a bezel. Decide on the implementation and which bezels best suit your applications. The indicator light insert can be used to reserve space for indicator lights and the blank plug can be used to set aside positions for future options. Switches: Determine the functions needed and select the electrical diagrams that match them. Then indicate the voltage required: 12 or 24 volts. Connectors: There is one standard connector plug and terminal for both the switches and indicators. Upon request, these components can be supplied loose, in the form of a 7 pigtail, or as part of a custom wire harness. Lenses: Select the colors of the lenses and the symbols needed to identify the functions of the switches. Custom made symbols can be designed upon request. There is a tooling charge associated with the creation of a customized symbol. A minimum order of 25 lenses is required. Indicator Lights: Indicator lights can be combined with the bezels and inserts to create indicator light modules. See Appendix B for more information about the indicator lights. Other Parts and Accessories: A rheostat is also available for the Modular Switch System. It can either be placed in the flush mount bezels using the bezel insert or individually panel mounted. Although not shown, panel mount switches are available for those applications that cannot use a flush mount bezel. These switches are in the same family as the flush mounts and share many of the same features and components.

9 Appendix A-9 Switch Assembly Part Number Composition The modular part system for switches consists of a string of 11 numbers divided into 4 segments. Type of Switch Voltage Lens Color Lens Symbol XXXX -XX XX XXX A custom built switch can be easily constructed by following these 4 simple steps: Step #1: Type of Switch Select the type of switch that best suits the application. We have a wide variety of either panel mounted or surface mounted switches to choose from. Refer to Page A-8 for a chart of part numbers. Step #2: Voltage No. Voltage Volts Volts Step #3: Lens Color No. Color 38 Amber 39 Green 70 Red Step #4: Lens Symbol Select the symbol graphics that represent the switch s function. Choose one from either our library of symbols or design a customized symbol. The symbols are printed in white on green, blue, and red lenses and black on the amber lenses. See page A-11 for further details. Select the voltage required: 12V or 24V. This is primarily used to determine the voltage of the illumination. The switches are designed to operated at either voltage 71 Blue Graphics are printed on color lenses. Choose the color of the lens that fits the application. An example of the modular switch assembly: A customer wants an ON/OFF, single pole, single throw, flush mount switch to control headlights. Referring to the switch part number chart, they choose the 4769 switch. They know that the application is 12 volts, which is designated by the number 12. They want a blue lens, which is designated by the number 71, with the Headlight graphic on it (lens symbol # 055). Combining these segments according to the table at the top of the page creates the part number They can now order their customized switch using this number. Assembled U.S.A. This part number system primarily applies to orders for individual, fully assembled switches and lenses.

10 Connectors, Terminals, and Pigtails Appendix A-10 Connectors and terminals are available for the flush mount switches. These standard components will fit the entire line of NP switches. They can come either as part of a 7 pigtail, a custom wire harness, or as individual pieces.
