Analyzing a Force Displacement Curve of a Tactile Dome

A force displacement curve is a good way to visually look at the mechanical function of a switch. The curve primarily shows two things – (1) the amount of force needed to actuate a switch from its open position to closed position, and (2) the amount of travel the switch undergoes from the open position […]

Choose Your Circuit Plating Wisely

When choosing your plating, keep in mind that each time a tactile dome is pressed that the legs or outer perimeter of the dome flexes. This can rub on the circuit and cause deterioration of the circuit pad over time. Both nickel and gold plating are options, but the type of plating depends on the […]

Placing Metal Domes in Membranes Can be Tricky

Placing metal domes quickly and accurately in membrane applications can be tricky. Typically, domes arrive in bulk form and are packaged in jars. Getting domes placed quickly can be challenging and “double doming” common. At Snaptron, we have invented a proprietary technology that allows for fast placement and assures only one dome is placed in […]

The Importance of Venting a Metal Dome

The movement of air in and out from under the dome is called “venting” and it is important to have so the metal dome functions properly. Lack of venting can cause adverse effects on the feel and function of the switch. Venting metal domes is crucial in order for the dome to feel the way […]
