Description: Hand operated rotary switches offer cost-effective solutions for complex contact switching functions, ensuring safe disconnection from the power supply. They can be configured for both simple and complex operations, such as a 9 pole isolating switch with specific contact requirements.

Specifications: The product range includes models R6, R16, Minirotary, and R40, with thermal ratings from 6A to 40A and a rated voltage of 690V. Position indexing options range from 300 to 900 degrees, and all models come with a standard operating knob.

Switching Characteristics: These switches are rated for various AC applications (AC20A, AC21A, AC22A, AC23A) with different current and power ratings at specified voltages. They have a rated short time withstand current and are compatible with specific BS 88 backup fuses.

Technical Specifications: Built to BS EN 60947-3 standards, the switches have a mechanical life exceeding 0.5 million operations. They feature finger-protected terminals and various contact materials.

Product Descriptions: The R6 and R16 models are suitable for common functions like isolation and meter selection. The Minirotary is versatile and ideal for rail applications due to its durability. The R40 offers high versatility with multiple indexing options.

Catalogued Items: Various sequences and configurations are available, including unrestricted and restricted positions with options for make-before-break and electrically separate contacts.

Accessories: Accessories include padlocking handles, multi-position locking handles, and knob actuators with IP65 protection. Specific configurations and mounting options are detailed for each accessory type.

Key Actuators - Single Hole Fixing: Ø22 and Ø32 mounting options are available for key actuators with IP65 protection. Various locking positions are available, with specific sequences noted for each type. The '300' and 'DC800' key series are standard, with additional key differences available upon request. Key actuators must be prefixed to switch references and cannot be sold separately.

Alternative Knobs: Several types of moulded and die-cast knobs are available, including skirted knobs and pistol grip handles. These are supplied either fitted to switches or as loose spares, with specific catalogue references provided for each type.

Extended Shafts and Contacts: Extended shaft options are available with specific projections. Gold surfaced contacts are offered for low power circuits, with gold flashed and plated options for enhanced durability.

Additional Features: The document details IP65 sealing kits, base mounting options, faceplate padlocking devices, and additional terminal protection, all designed to enhance the functionality and security of the rotary switches.

Conclusion: Craig & Derricott's 'Classic Range' of rotary switches provides a wide selection of assemblies, focusing on bespoke solutions for specific industry needs. Additional components such as enclosures and indicator plates are available in separate data sheets.
