The datasheet discusses the “7000 Series Miniature Rocker & Lever Handle Switches,” which are suitable for a variety of uses including telecommunications, instrumentation, and medical equipment. These switches offer features such as multiple poles and positions, along with a range of actuator and termination options to fit different requirements.
Specifications outlined in the datasheet establish the contact rating for two types of contact materials. B contact material has a max rating of 0.4 VA at 20 V AC or DC, and Q contact material allows for 5 AMPS at 120 V AC or 28 V DC, with an alternative rating of 2 AMPS at 250 V AC. Details on additional ratings can be found on page G-20 of the full datasheet. The electrical life varies by model, with 7XO1 and UXI models handling 100,000 make-and-break cycles at full load, while other models sustain 40,000 cycles. The contact resistance is below 10 mΩ initially, and the insulation resistance stands at a minimum of 10⁹ Ω. A dielectric strength of a minimum of 1000 Vrms and an operating temperature range from -30°C to 85°C make these switches robust for different environments.
As for materials, the switches are built with cases made of glass-filled nylon or diallyl phthalate, both flame retardant and heat stabilized with a UL 94V-0 rating. Actuators are comprised of black nylon, and frames vary depending on their position. Bushing materials are brass or nickel-plated zinc, while the housing is stainless steel. Contact materials include copper alloy and coin silver, with either gold or silver plating detailed. The datasheet assures that models supplied with specific contact materials are RoHS compliant, ensuring adherence to environmental standards.
The Build-A-Switch section provides a modular approach for ordering by selecting options from various categories including switch function, contact material, actuator type, terminations, actuator color, frame color, and seals. Switch functions come in variations from single-pole (SP) to four-pole (4P), each with different ‘On,’ ‘Off,’ and ‘Momentary’ (Mom.) positions. Contact materials range from gold to silver plating. A diverse selection of actuator types and termination options are available to accommodate different assembly requirements. Detailed on pages G-4 through G-24, with additional custom options accessible through customer service, these selections confirm compatibility with all “bottom-wash” PCB cleaning methods. Lastly, seal options and actuator/frame colors are selectable to ensure the switch matches specific design and functional criteria.
Note that the specifications and materials listed apply to switches with standard options. For specific or custom switches, the datasheet encourages consultation with the Customer Service Center. All models include an epoxy terminal seal for durability. Dimensions and specifications are subject to change, as denoted by the stated date of revision.
