WHAT IS IT?
The SS12D00 slide switch, drawn at true scale: a steel case 8.6 x 4.2 mm, a black knob and three
legs 2.54 mm apart. It is a true analog part:
  * SPDT: the common leg C joins leg 1 or leg 3, through a small contact resistance.
  * Click it at Run and the knob slides. The sheet keeps that position after Stop, and you can pick
    it while stopped.
  * The contact breaks before it makes, and it bounces for a few ms, so a sketch that does not
    debounce shows the trouble.
  * The small dot on the case opens the pop-up: the contacts, the live values, graphs, an event log
    and a check page.
The body is drawn as on the real part and to true scale against our Arduino.
The TEP signature and the pop-up are TEP additions.

ONE DEVICE (search "SWITCHSLIDE" in Pick Devices):
  SWITCHSLIDETEP   "Slide Switch V1.0" in TEPSLIDE.LIB (category Switches and Relays > Switches),
  prefix SW, model TEPSLIDE.DLL. Pins 1, C and 3.

THE POP-UP
Click the small dot at Run; a click anywhere else on the switch flips it. Tabs:
    Switch     LEFT or RIGHT, the switch, the contacts with the live path, and eight live values.
    The toolbar: Flip.
    Graphs     the live values over the last 2, 6 or 15 s. Live / Freeze.
    Event log  every change and warning; filters All / Changes / Warnings, Pause, Clear
    Check      what the part is doing and what to look at, each with a verdict (green = fine, amber
    = check, red = wrong)
    Settings   theme, text size, open at Run, window size

TEST STATUS
V1.0: verified in Proteus 8.5 on 31 Oct 2026 (the demo project as shipped: an A4 sheet, an Arduino UNO V4.0).
What the runs showed (the model's own numbers and the sketch's monitor):
  * The project loads and starts cleanly. SW1 left: D2 LOW, the LED on D8 blinking slowly. Flipped
    right: D2 HIGH, blinking quickly, and the monitor said so after its 20 ms debounce.
  * The contact made 5 edges as it landed, in about 3.6 ms, and broke before it made.
  * SW2 moved the current from the green LED to the blue one, 9.5 mA, with no help from the sketch.
    The knobs stayed where they were after Stop.
  * The pop-up: Switch, Graphs, Event log, Check - all four pages followed the run.

INSTALLATION (about 2 minutes)
1. Close Proteus. Extract the WHOLE ZIP to a normal folder (e.g. Desktop).
2. Copy everything in "Proteus Library Files" (TEPSLIDE.LIB, TEPRESISTOR.LIB, TEPLED5MM.LIB and our
Arduino library V4.0, ArduinoV4TEP.LIB, with the ARDUINO UNO V4.0 used by the demo) to the LIBRARY
folder of Proteus, for example:
     C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\LIBRARY
   (use the folder that already holds Proteus's own .LIB files).
3. Copy TEPSLIDE.DLL, TEPRESISTOR.DLL, TEPLED5MM.DLL and TEPARDUINO.DLL from "Proteus Model Files"
to the MODELS folder (...\Proteus 8 Professional\MODELS).
4. Delete TEPSLIDE.IDX from the LIBRARY folder if it is there (Proteus makes a new index).
5. Start Proteus. In Pick Devices (P) search "SWITCHSLIDE".

RUN THE DEMO
"Proteus Simulation\Slide-Switch-Modes-ArduinoUnoV4.pdsprj" (an A4 sheet) - keep the .hex file and
the DLLs beside the project.
  ARD1:   Arduino UNO V4.0 running Mode_Select_Demo.hex, its serial monitor built in (window "TEP
  Arduino UNO - ARD1").
  SW1:    1 to GND, 3 to +5V, C to D2. The sketch reads a clean LOW or HIGH.
  D1:     a red LED on D8 through R1: it blinks slowly or quickly to match SW1.
  SW2:    C to +5V, and it picks which LED gets the power: D2 (green) or D3 (blue), through R2 and
  R3. No sketch is involved.
  1. Press Run. D1 blinks slowly and D2 is lit.
  2. Click SW1. D1 blinks quickly, and the monitor says so.
  3. Click SW2. The green LED goes out, and the blue one lights.
Closed the monitor? Click the UNO's USB port.

WIRING (the same in Proteus and on a real board)
  GND - 1 ; +5V - 3 ; C - pin : a pin reads LOW or HIGH with no pull-up
  +5V - C ; 1 - one load ; 3 - the other : a switch that picks between two loads
REAL HARDWARE:
 * The small switches are for signals, up to about 300 mA.
 * Do not use one on the mains.
 * While the knob moves, C is joined to nothing for a moment. A sketch reads a floating pin then, so
   a pull-up or a debounce still helps.

THE DEMO SKETCH ON THE SERIAL MONITOR (Mode_Select_Demo V1.0, 9600 baud)
There are no commands. The sketch prints a line when SW1 moves.
EXPECTED MONITOR OUTPUT
  Slide Switch demo - The Engineering Projects
  SW1 is LEFT: slow

PROPERTIES (double-click the part > Edit Properties)
  Contact resistance, ohm    0.03
  Contact bounce, ms         3
  Position while stopped     Left or Right
Every run starts again from the properties.

LINKS.INI (OPTIONAL)
The Help page cards of the pop-up open web pages. To point them somewhere else without a new DLL,
put a text file named links.ini next to TEPSLIDE.DLL with lines KEY=URL, for example:
  ARTICLE=https://www.theengineeringprojects.com/...
Keys: WEBSITE, FORUM, BUG_REPORT, FEATURE_REQUEST, ARTICLE, USER_GUIDE,
UPDATE_CHECK, DONATE. Only http:// and https:// links are used; lines starting
with # are comments.

TROUBLESHOOTING
* A click opens the pop-up: you clicked the small dot. Click the case or the knob to flip it.
* The sketch sees several changes: that is contact bounce. Debounce it, or set the bounce to 0.
* The part is at the wrong end at Run: pick the Position while stopped.
* The part is not simulated: TEPSLIDE.DLL is missing from MODELS and from the project folder. No UNO
  / no monitor window: TEPARDUINO.DLL is missing, or click the UNO's USB port.

LICENCES AND THIRD-PARTY NOTES
* The model (TEPSLIDE.DLL), the symbols and artwork, the other parts of ours in the demo and the
  Arduino Library V4.0 (ArduinoV4TEP.LIB / TEPARDUINO.DLL, with its built-in TEP Serial Monitor
  Advance) are made by The Engineering Projects. The models use only standard Windows libraries; no
  Visual C++ redistributable is needed.
  The C++ source code is not included.
* Arduino UNO V4.0 (ArduinoV4TEP.LIB / TEPARDUINO.DLL, our Arduino Library V4.0 - its
  microcontroller is Proteus's own AVR model): The Engineering Projects,
  https://www.theengineeringprojects.com/2026/10/arduino-uno-library-for-proteus-v40.html
* The .hex file is built from the demo sketch and the Arduino AVR core 1.8.6, which includes
  LGPL-licensed code; its source code is available at
  https://github.com/arduino/ArduinoCore-avr/tree/1.8.6
* Proteus is a product of Labcenter Electronics and is not included. Arduino is a trademark of Arduino SA.
  This library is not made or endorsed by Arduino or Labcenter.

REBUILDING THE FIRMWARE (OPTIONAL)
The HEX file is supplied; Arduino IDE is not needed to run the demo. To edit the sketch, open
Arduino Code\Mode_Select_Demo\Mode_Select_Demo.ino, select Arduino Uno and use Sketch > Export
Compiled Binary. Replace the simulation's .hex with the exported HEX. The sketch needs 3,166 bytes
of flash and 210 bytes of RAM.

MODEL SCOPE AND LIMITS
Modelled: the contact resistance, break before make, contact bounce, the current rating on the Check
page.
Not modelled: wear, a contact that lifts under high current.
