Key switch – safety and control in your home

This single-pole key switch from the Simon 55 series is a practical solution for electrical installations where additional access control or protection against unauthorized switching is required. Ideal for technical rooms, workshops, or anywhere you need to be sure that the device will only be switched on by authorized personnel. Thanks to the compact size of the module (for flush mounting), it can be easily integrated into an existing installation.

Functionality and installation

The switch is designed for 250V voltage and 5A current, making it suitable for most standard lighting and socket circuits. The key-locked mechanism ensures reliable operation. The set includes two keys, which increases ease of use. Installation is done with claws or screws, which makes installation easier even for less experienced users. It is worth remembering that to obtain an IP44 degree of protection (splash protection), a dedicated keycap seal must be purchased separately.

Design and quality of workmanship

The Simon 55 series is characterized by a modern design and high quality workmanship. The module made of durable halogen-free PC plastic is resistant to mechanical damage and ensures long-term operation. The matte finish gives it an elegant look that blends perfectly with various interior styles. The availability of frames in many colors and materials (glass, aluminum) allows you to match the switch to individual preferences and room decor. The product meets safety standards and complies with applicable regulations.
