Safe Break action : The IDEC original “fail-safe” solution for E-stops



IDEC X-series switches use “Safe Break action”, a unique reverse-energy structure that disconnects normally closed contacts, guaranteeing shut-off even if the emergency switch is damaged or the contact blocks separate.


  • Improper installation or excessive force may render Conventional E-stops incapable of stopping a machine.
  • In the event the switch is damaged due to excessive shocks, the NC contacts will turn off, thus stopping the machine (patented design).
  • By automatically turning off the machine when the contact block or actuator are improperly installed or damaged, all IDEC E-stops meet or exceed International safety standards (ISO 13850 and EN60947-5-5).
