Safe Break Action
When the contact block is detached from the operator, the
NC contact opens (OFF).
When the contact block is detached from the operator, the cam
directly opens the NC main contacts (contacts are off).

Safety for operators, machines and systems
Excellent safety mechanisms including a
mechanical indicator that shows contact status.
With XW series emergency stop switches, the potential energy
level of the latched status is lower than that of the normal status.
When the switch is damaged due to excessive shocks, the NC
contacts will turn off, thus stopping the machine (patented design).
IDEC's sleek, smooth
design reduces operator's
stress and fatigue.
The safety mechanism ensures the XW
contacts open (safe) even when damaged by
excessive shocks (reverse energy structure,
safe break action).
Non-illuminated Illuminated
Direct Opening Action
Complies with International Standards
All normally closed contact elements of an
emergency stop devices shall have a direct opening
action (positive opening action), according to annex
K of IEC 60947-5-1. (IEC 60947-5-5; 5.2)
Complies to international safety standards
The emergency stop signal shall be maintained
until the emergency stop device is reset
(disengaged). (IEC 60947-5-5; 6.2)

(Actual Size)
Mechanical Indicator – the operator
body of the switch is green when
the contacts are closed, the green is
hidden when the switch is actuated.
The smooth and ridge-free
button surface prevents dust
build-up, and is also easy to
clearn. Ideal for applications such
as food processing machines.
