What type of contact resistance do I require? The circuit pad base is often copper, which will oxidize if not plated. Nickel has […]

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 […]
