Conventional Emergency Stop Switches
With the XA and XW emergency stop switches, the energy level of the “on”
(closed) NC contacts is higher than that of the “off” (open) contacts. If the
contact block falls off due to excessive shocks, the NC contacts are always
inclined to turn off, thus ensuring safety by stopping the machine.
