Product information

Description

The Kontakt-Simon K303 is a high-quality pushbutton switch engineered for seamless integration into electrical installations. Constructed with a robust plastic housing, this device offers a reliable momentary contact mechanism suitable for both residential and commercial environments. Designed to operate at 16A and 250V AC, it provides a stable and functional solution for controlling various electrical circuits where a momentary signal is required.

Advantages

This switch stands out due to its compact design and durable construction, ensuring long-term performance in standard indoor electrical systems. The momentary action is precise and responsive, making it an excellent choice for applications requiring temporary activation. Its lightweight build and standardized dimensions allow for easy installation into existing wall boxes or modular systems, providing a clean and professional finish to any electrical setup.

Suitable for

  • Lighting control systems requiring momentary activation
  • Doorbell or buzzer circuits
  • Industrial control panels for temporary signal transmission
  • Modular electrical installations in offices and homes

When it may not be suitable

The Kontakt-Simon K303 is not intended for outdoor use or environments with high moisture, as it carries an IP20 protection rating. It is also not suitable for applications requiring a latching or maintained contact state, as it is strictly a momentary pushbutton switch.

Key specifications

  • Rated current: 16A
  • Rated voltage: 250V AC
  • Protection rating: IP20
  • Material: Durable plastic
  • Width: 22 mm
  • Depth: 34 mm
  • Weight: 26 g

How to use

The switch should be installed by a qualified professional in accordance with local electrical regulations. Ensure the power supply is disconnected before beginning the installation. Connect the electrical wires to the designated terminals on the back of the switch. Once secured within the mounting frame or wall box, the switch is ready for operation. Pressing the button will complete the circuit momentarily, and releasing it will break the connection.

What to consider before purchase

  • Verify that the momentary contact mechanism meets your specific circuit requirements.
  • Ensure the installation environment is dry and free from dust, as the IP20 rating offers no water protection.
  • Check the dimensions to ensure compatibility with your existing wall plates or modular frames.

Usage recommendations

For optimal safety and longevity, do not exceed the rated current of 16A. Regularly inspect the switch for any signs of physical damage or loose wiring to maintain system integrity.
