‘Operating range’ is the range where can get adequate electrical contacts when applied force to the spring.
‘Amount of displacement is the distance that the spring moves from the initial position (= no load) when applied force to the spring.
‘Working range’ is the distance from PCB surface to top of the spring inside operating range
