Ultra-low Profile Dome Array
B3DA
Ultra-low Profile Dome Array With Dust-Proof
Construction and Crisp Clicking Action
? No soldering required. Attach directly to PCB to make an ultra-low
profile tactile switch.
? Matrix adhesive used to create highly dust-proof construction
with good ventilation. Omron's unique circular contact action
ensures a high level of resistance to foreign matter.
? Lower profile, lighter weight, and crisp clicking action.
? Customization of Dome Array available upon request
(i.e., silver plating, number of contacts, shape, etc.).
? RoHS Compliant.
