Overview of EO2O Series Pushbutton Switches
Designed for durability and reliability, the EO2O Series of sealed, snap-acting, momentary pushbutton switches offer a range of features suitable for various applications including instrumentation, telecommunications, networking equipment, computers, and peripherals. The switches are sealed to endure machine soldering temperatures and pressure wash cleaning, enhancing their usability in harsher environments.
Key Features
The switches boast a long-service contact design, a snap-fitting plunger option, and a disposable splashproof boot. They are RoHS compliant, indicating adherence to restrictive use of hazardous substances. Certain models within the series present multi-pole contacts, while all versions offer a choice of contact materials to meet specific requirements. With a contact rating up to 0.4 VA max at 20 V AC or DC, the switches are capable of handling 60,000 make-and-break cycles at full load.
Construction Materials
Constructed with glass filled nylon 6/6 for the case and bushing, the switches hold a flame retardant rating of UL 94V-0. Contacts are made from a copper alloy or coin silver, both with gold plating over nickel plate to ensure good conductivity and durability. Terminals are sealed with epoxy, and the switch support is crafted from brass or steel with a matte-tin finish.
Performance Specifications
These switches feature an electrical life of 60,000 cycles at full load, denoting consistent performance across numerous actuations. Contact resistance is maintained below 50 milliohms, and insulation resistance starts at 100 megaohms minimum, with a dielectric strength of 1000 Vrms at sea level. Operational temperatures range between -30°C and 75°C, ensuring functionality across various climates.
Customization and Ordering
Clients are provided with the “Build-A-Switch” capability, where desired options can be chosen from categories detailed on pages A-22 to A-28. Models accommodate SPDT or DPDT switch functions with various plunger heights and bushing types. Termination styles are abundant, offering right angle, vertical, PC thru-hole, snap-in, and V-bracket configurations, among others.
Additional Information
Details such as dimension standards in inches and millimeters, along with note blocks, give customers guidance regarding the specifications and customization options available for each switch. The datasheet invites potential users to consult the Customer Service Center for specific and custom switches to ensure all unique requirements are met effectively.
