When they are working they stop the machine within millimeters, it's when they stop working you pucker up.!!. . . But that's the case with any switch or safety circuit, it's only safe while it's working so factor in for when the shit hits the fan and they stop working which in this case, the only safe solution is a strong bump stop and a fault signal which is hard-wired into the E-stop system for when the drives faults.!
