Metal Domes 3mmRound Bonsda SD-X3C16-1D-DN

Concave nickel-coated metal shrapnel in a round form with a strength of 160 gf

Product Characteristics

Tactile metal domes are momentary switch contacts that become normally open switches when used with a printed circuit board, flex circuit, or membrane. They are placed on printed circuit boards through pressure-sensitive adhesive tape, captured in a pocket design。

Overview

In the static state, the tactile metal spring is in contact outside the main pad. When briefly pressed, they come into contact and make contact with the secondary path, thereby closing the circuit. Many different shapes and forces can be used to suit your specific application. You can use them as mechanical switches, electrical contacts, and tactile switches.
