A stop kontak is an electrical outlet or socket designed to connect electrical devices to a power supply. It typically features multiple sockets, allowing users to power several devices simultaneously. Stop kontaks are widely used in residential, commercial, and industrial settings due to their convenience and versatility. They are essential for powering appliances, tools, and electronic devices.
This circuit is designed to control a pump using a contactor that is manually operated by a switch and can be overridden by an emergency stop. The contactor enables power from an AC power outlet to the pump, and the emergency stop can interrupt the power circuit for safety purposes.

This circuit is an emergency alert system that uses a NUCLEO-F072RB microcontroller to send SMS alerts and make calls via a SIM800L GSM module, while obtaining location data from a GPS NEO 6M module. The system is powered by a Li-ion battery and includes a TP4056 module for battery charging and protection, with a rocker switch to control power to the microcontroller.

This circuit features an Arduino UNO connected to an HC-SR04 ultrasonic sensor for distance measurement and a SIM800L GSM module for communication. The Arduino controls an LED, which lights up based on the distance detected by the ultrasonic sensor. When a certain distance threshold is exceeded, the Arduino uses the SIM800L module to make a phone call, indicating motion detection. A 48V to 5V converter supplies power to the SIM800L and the ultrasonic sensor.

This circuit is an automatic passenger counter and temperature sensor system powered by a solar charger. It uses an ESP32 microcontroller to interface with two capacitive proximity sensors for counting passengers and a DHT22 sensor for monitoring temperature and humidity, with data being sent to a Blynk mobile app and Google Sheets for real-time tracking and logging.
Open Project in Cirkit DesignerBelow are the general technical specifications for a standard stop kontak. Note that specifications may vary depending on the model and manufacturer.
The pin configuration of a stop kontak depends on the socket type. Below is an example for a Type C socket, commonly used in Europe and Asia.
| Pin Name | Description | Notes |
|---|---|---|
| Line (L) | Live wire carrying current | Connects to the power source |
| Neutral (N) | Returns current to the power source | Completes the circuit |
| Ground (G) | Safety ground connection | Optional in some socket designs |
For other socket types, refer to the specific regional standards.

While a stop kontak is not directly connected to an Arduino UNO, it can be used in projects involving relays to control high-power devices. Below is an example of using an Arduino UNO to control a device connected to a stop kontak via a relay module.
/*
Example: Controlling a device connected to a stop kontak using a relay module.
This code turns the device ON for 5 seconds and then OFF for 5 seconds in a loop.
*/
const int relayPin = 7; // Pin connected to the relay module
void setup() {
pinMode(relayPin, OUTPUT); // Set relay pin as output
digitalWrite(relayPin, LOW); // Ensure relay is off at startup
}
void loop() {
digitalWrite(relayPin, HIGH); // Turn the relay ON (device ON)
delay(5000); // Wait for 5 seconds
digitalWrite(relayPin, LOW); // Turn the relay OFF (device OFF)
delay(5000); // Wait for 5 seconds
}
Note: Ensure proper isolation between the low-voltage Arduino circuit and the high-voltage stop kontak circuit when using a relay.
