Reach for the “Safe Break Action”
When the contact block is removed from the operator the main contact
(NC) is forced to open (OFF). When removing the contact block, the cam
provides a direct opening action to open the contact.

Unrivalled safety:
IDEC Emergency Stop Switches include exclusive technology that has
changed the way E-Stop switches are designed. This “safe break action”
concept provides greater levels of human safety.
Conventional E-Stop switches are designed with spring pressure on the
Normally Closed (NC) contacts, keeping them in the closed position and
allowing a machine to operate. But improper installation or excessive force
to the button in an emergency may break or dislodge a vital part, causing
the spring loaded contact to stay closed. This situation renders the E-Stop
incapable of stopping the machine, and can lead to catastrophic events,
personal injury and possible loss of life.
However, IDEC X-Series E-Stops use a “safe break action,” which reverses
the energy direction and uses the spring-pressure to guarantee that the NC
contacts will open if the emergency switch is damaged or the contact blocks
separate due to excessive force. This is the E-Stop switch you can rely on in
a life threatening situation.

X-Series E-Stops have lower potential energy in the
“Locked” (Latching) position than in the “Normal”
(Reset) position. When the switch is damaged from an
excessive shock, the main contact (NC) moves toward
the OFF (Safe) position.
Direct Opening Action
Even if the contacts are welded, the force applied
on the button directly opens the contact.
Rated Insulation Voltage: 250V minimum
Rated Thermal Current: 5A minimum
Safety Interlock Mechanism
Contacts are opened when the operator is locked, and
remain opened until the operator is unlocked
intentionally. (IEC60947-5; 6:2)
Two E-Stops in One
Push to lock, Pull/Turn to Reset
The X-Series E-Stops can be reset either by pulling or
turning the button. With traditional E-Stops, you need to
choose between Push-Pull or Pushlock Turn Reset. With
the IDEC X Series E-Stops you get both in one switch.
(Except XN4E which is only Pushlock Turn Reset).
