E Series Sealed Miniature Toggle Switches Overview
The E Series Sealed Miniature Toggle Switches provide robust solutions for applications in telecommunications, instrumentation, and medical equipment. The switches come with a UL 94V-0 Nylon case and bushing, indicating a high standard of flammability rating. They are also sealed against contaminants from soldering and cleaning processes, making them reliable for use in sensitive environments.
Key Features and Benefits
These toggle switches offer multi-position actuation and ESD protection, with RoHS compliant models available. They boast high durability, with electrical life up to 40,000 cycles for some models and a contact resistance that starts below 10 mΩ. The switches’ insulation resistance is greater than or equal to 1 GΩ, highlighting their safety and efficiency.
Specifications and Models
The contact rating varies by model, with the B contact material rated for up to 0.4 VA max and the E Series models ranging from 3 to 7.5 AMPS across various voltages. For detailed ratings, page F-24 in the datasheet should be consulted. The switches can withstand electrostatic discharge (ESD) up to 20,000 V DC and have a dielectric strength of at least 1,000 Vrms at sea level.
Operating Conditions and Materials
These miniature toggle switches are suitable for operating temperatures from -30°C to 85°C and are designed to meet IP57 protection standards, ensuring full-scale voltage protection and resistance to temporary immersion. The components include a glass-filled nylon 6/6 case and bushing, brass or steel switch support, and various contact and terminal materials including options with gold or silver plating.
Ordering Information and Custom Options
To create a custom switch, customers can utilize the Build-A-Switch service by selecting options from each category provided in the datasheet between pages F-18 to F-24. Several switch functions are available, with SP, DP, and 3P configurations, different actuator heights, and multiple termination styles and contact materials. The F1 conductive bushing option is designed to dissipate high voltage from the actuator to the ground, and it is available with certain models.
Environmental Compliance
All models that come with R, 8.R, Q, B, or G contact materials comply with RoHS regulations, affirming their manufacture with restricted hazardous substances.
Please note that specifications and materials listed pertain to switches with standard options. The datasheet encourages consulting with the Customer Service Center for information on specific and custom switches. Importantly, all models are process sealed, capable of withstanding machine soldering temperatures and pressure wash cleaning methods.
Additional Resources
For further technical specifications, dimensions, and part numbers, reference has been made to the schematics and tables on the datasheet, specifically pointing to page F-17 for switch functions and F-18 for ordering. It also highlights that specifications and dimensions are subject to change and advises checking the C&K website for the latest information.
