Description: The document provides technical specifications for hand-operated rotary switches used in heater applications. These switches are cost-effective for complex contact switching and ensure safe disconnection from the power supply. They are applicable in various heater control scenarios, including water heaters and injection tool heater circuits.

Specifications: The switches are available in different models: R6, R16, Minirotary, and R40, each with varying thermal ratings, position indexing options, and rated voltages. The switches are designed to handle different current ratings and have specific short-time withstand capabilities. They feature finger-protected terminals and are made from materials like Ag/Ni and Ag/CdO.

Switching Characteristics: The document details the AC switching characteristics for each model, including current ratings at different voltages and power ratings for specific applications.

Mechanical Features: The switches have a mechanical life of over 0.5 million operations and come with standard operating knobs. They are designed for easy termination with specified termination sizes and maximum connecting cable sizes.

Accessories and Customization: Various accessories are available, including multi-position locking handles, knob actuators, and key actuators. The document also describes alternative knobs and extended shafts for customization. Gold-surfaced contacts and IP65 sealing kits are available for enhanced performance.

Applications and Recommendations: The switches are suitable for isolation duties and are favored in rail applications due to their durability. The Minirotary switch is noted for its versatility and is preferred by control panel manufacturers for its compact design.

Conclusion: Craig & Derricott offers a wide range of rotary switch assemblies and bespoke solutions to meet specific industrial needs. Additional components like enclosures and indicator plates are available in separate data sheets.
