E Series Sealed Miniature Rocker and Lever Handle Switches

This datasheet provides detailed information on the E Series Sealed Miniature Rocker and Lever Handle Switches, which are designed for use in applications like telecommunications, instrumentation, computers, and peripherals. These switches offer several benefits central to their performance and reliability, such as protection against contaminants from solder and cleaning processes and resistance to electrostatic discharge (ESD). All actuator options meet the ESD resistance requirement, withstanding up to 15,000 V DC. The actuators, case, and bushing are UL 94V-0 rated, ensuring the material’s flame retardancy, and the components are also RoHS compliant.

Specifications and Materials

Here is an overview of the important specifications: Models E1XX and E2XX series can handle 40,000 make-and-break cycles at full load, while E3XX models can endure 30,000 cycles. Moreover, the contact resistance is typically below 10 mΩ initially, the insulation resistance is greater than 10^9 Ω, and the dielectric strength stands at a minimum of 1000 Vrms. Operating temperatures range from -30°C to 85°C, and the switches can be soldered according to MIL-STD-202F and EIA RS-186E specifications.

Materials used in these switches include glass-filled nylon for the case and bushing, nylon for the actuator and pivot mounting bracket, spring steel for the frame, brass or steel for the switch support with matte-tin plating, and stainless steel for the mounting hardware.

Contact Rating and Terminations

The contact ratings vary: Models E1XX and E2XX can accommodate 7.5 AMPS at 125 V AC or 28 V DC; models E3XX can handle 5 AMPS at 125 V AC or 2 AMPS at 250 V AC. The contacts and terminals come in a variety of materials, such as copper alloy with gold, silver, or matte-tin plating. Detailed contact materials are given on page G-36 of the catalog.

Switch Function and Customization

Switch functions include single-pole and double-pole options with various on, off, and momentary positions. A ‘Build-A-Switch’ feature gives users the ability to specify desired options across various categories such as switch function, contact material, actuator type, terminations, seal, actuator color, frame color, and metal frame color. The datasheet also diagrams the switch function positions and terminal connections specific to model numbers, indicating how each configuration operates.

In conclusion, the datasheet serves as a comprehensive guide on the E Series Sealed Miniature Rocker and Lever Handle Switches, outlining their technical specifications, construction materials, and custom order process. The switches’ robust design coupled with customization ensures they are suitable for a wide range of industrial and consumer applications, aligning with necessary safety and performance standards.
