14 Button and Activation Specifications
The button requires a force of 3 -5 N (Newton - si units). Another way to explain this:
6 – 18 oz of pressure over time applied, which is between 125 –300ms (0.15 –0.3 seconds).
Slapping or sliding your ngers across the button will not activate it. It requires pressure over time. The outer
edge of the button will not be that sensitive. Normal use of the button would be someone rushing to activate it
and using their hand, nger, arm, knee, forehead, etc.
No other piezoelectric button on the market will function as well.
The only differences between the analog and IP buttons are the output on the wires and the state of the button,
N.O or N.C. The button can and piezo elements are identical. The analog button (2 wire) is N.O. (Normally
Open), and closes momentarily when pressed. The digital button (3 wire) is N.C. (Normally Closed) and when
pressed the state goes to open momentarily, which is translated to a P then R data output to the IP1500/
IP2500/IP5000 boards.
