Grove - Switch(P)

This Grove – Switch is a mini SPDT slide, great for “ON/OFF” situations. It is a reliable switch of great build quality that we adopt it on many of our boards. You should stock some for your Grove prototyping system.

What does “P” mean? “P” stands for “panel mount” in this product.


Product Version Changes Released Date
Grove-Switch(P) V1.0 Initial Jul 2012


  • Grove Interface
  • Easy to use
  • Basic Grove element


More details about Grove modules please refer to Grove System

Platforms Supported

Arduino Raspberry Pi BeagleBone Wio LinkIt ONE


The platforms mentioned above as supported is/are an indication of the module's hardware or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.

Getting Started


If this is the first time you work with Arduino, we firmly recommend you to see Getting Started with Arduino before the start.

Play With Arduino


  • Step 1. Prepare the below stuffs:
Seeeduino V4.2 Base Shield Grove-Switch(P) Grove - Purple LED (3mm)

  • Step 2. Connect Grove-Switch(P) to D2 port of Grove-Base Shield.
  • Step 3. Connect Grove-LED to D6 port of Grove-Base Shield.
  • Step 4. Plug Grove - Base Shield into Seeeduino.
  • Step 5. Connect Seeeduino to PC via a USB cable.


If we don't have Grove Base Shield, We also can directly connect Grove-Switch(P) and Grove - Purple LED (3mm) to Seeeduino as below.

Seeeduino Grove-Switch(P) Seeeduino Grove - Purple LED (3mm)
5V Red 5V Red
GND Black GND Black
NC White NC White
D2 Yellow D6 Yellow


  • Step 1. Please copy below code to Arduio IDE and upload to arduino. If you do not know how to upload the code, please check how to upload code.
const int switchPin = 2;     // the number of the pushbutton pin
const int ledPin =  6;      // the number of the LED pin

int switchState = 0;         // variable for reading the pushbutton status

void setup() {
    // initialize the LED pin as an output:
    pinMode(ledPin, OUTPUT);
    // initialize the switch pin as an input:
    pinMode(switchPin, INPUT);

void loop(){
    // read the state of the switch value:
    switchState = digitalRead(switchPin);

    if (switchState == HIGH) {
        //turn LED on:
        digitalWrite(ledPin, HIGH);
        Serial.println("switch high!");
    else {
        //turn LED off:
        digitalWrite(ledPin, LOW);
        Serial.println("switch low");
  • Step 2. When we switch to high and the LED will be on. We also can see the Serial output as below.
switch high!
switch high!
switch high!

Play With Raspberry Pi


  • Step 1. Prepare the below stuffs:
Raspberry pi GrovePi_Plus Grove-Switch(P)
enter image description here enter image description here enter image description here
Get One Now Get One Now Get One Now
  • Step 2. Plug the GrovePi_Plus into Raspberry.
  • Step 3. Connect Grove-Switch(P) to D3 port of GrovePi_Plus.
  • Step 4. Connect the Raspberry to PC through USB cable.


  • Step 1. Follow Setting Software to configure the development environment.
  • Step 2. Git clone the Github repository.
cd ~
git clone https://github.com/DexterInd/GrovePi.git
  • Step 3. Excute below commands to monitor the switch status.
cd ~/GrovePi/Software/Python
python grove_switch.py

Here is the grove_switch.py code.

import time
import grovepi

# Connect the Grove Switch to digital port D3
switch = 3


while True:

    except IOError:
        print ("Error")
  • Step 4. We will see the switch status as below.
pi@raspberrypi:~/GrovePi/Software/Python $ python grove_switch.py
