Kontakt-Simon TW1K.01/111 Key-Operated Single-Pole Switch Module, 2-Position 0-I, N/O Contact, 5A 250V, Matte White

The Kontakt-Simon TW1K.01/111 is a professional-grade key-operated single-pole switch module designed to provide secure and controlled access to electrical circuits. This 2-position 0-I switch features a normally open (N/O) contact mechanism, ensuring that the circuit remains open until the key is turned to the active position. Finished in a clean matte white, this module is engineered for integration into standard electrical installations where restricted operation is necessary to prevent unauthorized use.

Advantages

This switch module offers a high level of security by requiring a physical key to operate the connected electrical load. Its robust construction ensures long-term reliability in various environments, while the matte white finish provides a neutral aesthetic that blends seamlessly with modern interior designs. The 2-position mechanism is intuitive to use, providing clear feedback during operation, and the 5A rating makes it suitable for a variety of standard lighting and control applications.

Suitable for

• Restricted access control for lighting circuits
• Securing electrical equipment in public or commercial spaces
• Preventing unauthorized operation of machinery or appliances
• Educational or office environments requiring controlled power access

When it may not be suitable

This module is not intended for high-power industrial applications exceeding its 5A current rating. It is also not suitable for outdoor environments without an appropriate IP-rated enclosure, as the standard module design does not provide protection against moisture or dust ingress.

Key specifications

• Switch type: Single-pole key-operated
• Positions: 2-position (0-I)
• Contact type: Normally open (N/O)
• Rated current: 5A
• Rated voltage: 250V
• Color: Matte white

How to use

The module is designed for installation into standard modular wall boxes or frames. Once installed, the switch is operated by inserting the provided key and turning it to the desired position. The 0 position keeps the circuit disconnected, while the I position closes the circuit. Always ensure the power is disconnected at the main breaker before attempting to install or wire the module.

What to consider before purchase

• Verify that the 5A current rating is sufficient for your specific electrical load
• Ensure compatibility with your existing modular frame system
• Confirm that the key-operated function meets your security requirements
• Check if additional mounting accessories are needed for your specific wall type

Usage recommendations

For optimal safety and longevity, ensure that the wiring is performed by a qualified electrician in accordance with local electrical codes. Do not force the key mechanism if resistance is felt, and keep the key in a secure location to maintain the intended access control.
