DT-Series Metal Domes

Just Added, A New Dual-Action Feature

DT-Series, otherwise known as dual-touch domes, can detect two different levels of force. DT domes can also close two electrical circuits in a single dome switch. The first contact occurs by applying light pressure to the switch, which provides no tactile feel. Additional pressure snaps the dome, closing the circuit—giving you the tactile feedback synonymous with traditional metal dome switches.

DT-Series domes can support the following features:

• Continuous Dual-Touch: Indicated as DTSD in the part number, these domes maintain two subsequent switch closures with one press.
• Backlighting: Indicated as DTBL in the part number, these domes have a hole in the center to provide a more intense backlighting effect.
• Custom: Options for different sizes, forces, travel, and plating are available. Contact us for more information on designing a custom DT dome.

DT-Series domes are available for purchase in bulk (loose in jars) or as part of a custom Peel-N-Place Array (mounted on adhesive tape). You can mount DT snap domes to various switching surfaces, including single or double-sided printed circuit boards, flex circuits, and membrane switches.

Note: DT-Series domes provide two different levels of user input. Domes indicated as DTSDXXXX will maintain contact through the first and second electrical closure.
