Reverse Energy Structure
With X series emergency stop switches, the potential energy
level of the latched status is lower than that of normal status.
In the event the switch is damaged due to excessive shocks,
the NC contacts will turn off, thus stopping the machine
(patented design).
Complies to international safety standards
Third Generation Emergency Stop Switches
Resetting
X series can be reset easily either by pulling or turning.
Safet and easy-to-use.
