Ultra-low Profile Dome Arrays
• No soldering required. Attach directly to PCB to make an ultra-low
• Matrix adhesive used to create highly dust-proof construction
• Lower profile, lighter weight, and crisp clicking action.
• Omron's unique circular contact action ensures a high level
• RoHS Compliant.
Application Examples
Use Dome Keys for the operating parts on various electronic devices that require low-profile controls, as follows:
• Operating switches with few mounted parts above PCBs.
• Small orders, where initial investment in Dome Arrays is not feasible.
• Applications requiring a single key only.
Specifications
Note: The Dome Keys are sold in units of 500 (20 sheets, with 25 Dome Keys per sheet). Orders must be made in multiples of 500 Dome Keys.
