How Does Demco SBS Stay N Play Detect How Hard to Apply Trailer Brakes

Question:

For Demco Duo Stay-In-Play and RVi Shadow systems, what is the intended relationship between deceleration and the force applied to the towed brake pedal? Each supplier references force and application time are dependent on deceleration proportional vs progressive technology. Which is it? Can you describe a graph of the relationship? By what principle does the deceleration sensor accelerometer operate for each supplier? How linear is the sensor output or is it a switch? Searching system for my 2014 Honda CR-V Thank YouI

We do carry the Demco DUO Stay N Play part # DM86VR which we has an internal accelerometer that senses inertia changes and combined with a brake signal will work to apply the towed vehicle brakes with a similar intensity. It is mercury switch inside unit that accurately detects the braking.

We do not carry the Shadow system so we don't have much info we can give on it.
