Keystone Electronics Tactile Key-Pad Dome Switches
Keystone Electronics Tactile Key-Pad Dome Switches are snap-action dome switches that provide positive feedback with an audible and tactile click. The domes are made of nickel-plated stainless steel, providing a reliable user interface with more than 1 million cycles. These switches are ideal for keypad arrays that require durability. The low profile is ideal for thin, lightweight applications or applications that need to be sealed or easily cleaned. The domes can be activated from finger pressure through a thin flexible membrane. The membrane can be sealed against the product chassis so cleaning fluids, dust, or weather will not damage the circuitry. If the device has a thicker or sculpted exterior package, the dome switches can be activated with an actuator for a more conventional push-button feel. Keystone Electronics Tactile Key-Pad Dome Switches offer a trip force from 7.8oz to 14.1oz and dome diameters of 8.4mm, 10.0mm, and 12.2mm.Features
