Appendix A-1

The Euramtec Modular Switch System hasthe flexibility to allow for the mixing andmatching of switches and accessories to fitany 12V or 24V application.

The NP heavy duty switches were designedand manufactured to meet the higheststandards of durability and reliabilityrequired by OEM manufacturers.

The “Snap-In” concept of both the switchesand panel mount bezels allow for quick andeasy installation.

Lenses for the switches are available inseveral colors. The graphics can be eitherselected from the library of pre-existingsymbols or custom made to suit the desiredfunction.

Mating connector plugs and terminals arealso available as accessories to the modularsystem.

How to Use The Modular Switch System

Appendix A-2

Bezels:The flush mount switches require the use of a bezel. Decide on the implementation and whichbezels best suit your applications.The indicator light insert can be used to reserve space for indicator lights and the blank plug canbe used to set aside positions for future options.

Switches:Determine the functions needed and select the electrical diagrams that match them. Thenindicate the voltage required: 12 or 24 volts.

Connectors:There is one standard connector plug and terminal for both the switches and indicators. Uponrequest, these components can be supplied loose, in the form of a 7” pigtail, or as part of acustom 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 withthe 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. SeeAppendix 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 flushmount bezels using the bezel insert or individually panel mounted.

Although not shown, panel mount switches are available for those applications that cannot use aflush mount bezel. These switches are in the same family as the flush mounts and share many ofthe same features and components.

Questions and Technical Support:For any questions or concerns about Euramtec’s products or their potential applications, pleasefeel free to contact us.

Switch Assembly Part Number Composition

Appendix A-9

The modular part system for switches consists of a string of 11 numbers divided into 4 segments.

A custom built switch can be easily constructed by following these 4 simple steps:

Step #1: Type of Switch

Select the type of switch thatbest suits the application.

We have a wide variety of eitherpanel mounted or surface

mounted switches to choosefrom.

Refer to Page A-8 for a chart ofpart numbers.

Step #4: Lens Symbol

Select the symbol graphics thatrepresent the switch’s function.

Choose one from either ourlibrary of symbols or design a

customized symbol.The symbols are printed in

white on green, blue, and redlenses and black on the amber

lenses.See page A-11 for further

details.

Step #3: Lens ColorStep #2: Voltage

Select the voltagerequired: 12V or 24V.

This is primarily used todetermine the voltage of

the illumination. Theswitches are designedto operated at either

voltage

Graphics are printedon color lenses.

Choose the color ofthe lens that fits the

application.

4769 - 12 71 055

A customer wants an ON/OFF, single pole, single throw,flush mount switch to control headlights.

Referring to the switch part number chart, they choosethe switch. They know that the application is 12

volts, which is designated by the number . They want ablue lens, which is designated by the number , with the

Headlight graphic on it (lens symbol # ). Combiningthese 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.

This part number system primarily applies to orders forindividual, fully assembled switches and lenses.
