The design feature of switches from the VL-C7XX series lies in their special compatibility with standard round mounting boxes having a minimum depth of at least 50 mm. These switches are designed in such a way that their installation does not require the use of “spacer tabs”, which are often used to strengthen the mechanism in the installation box.

Instead, the switch installation process involves the use of screws. The switch mechanism is securely fixed to the mounting box using screws, ensuring stability and reliability of fastening. This emphasizes the simplicity and efficiency of the installation process of VL-C7XX switches, making them convenient and functional elements of electrical systems.
