Exclusion of liability
No liability shall be accepted for any damage or operational faults caused by a
failure to observe these operating instructions. All further liability of the manufac-

Function
The contact element is actuated by means of the button. The contact elements
are also available with failure protection to maintain safety in the event of a volt-
age drop of the contact element of the push-button. This opens a contact when
the contact element is disconnected from the button. The failure protection thus
detects a fault and triggers the emergency stop function.
Please observe the wiring diagram on the contact element.
Release
- Twist release:
turning clockwise/counter-clockwise
- Key release:
only NHT04S
Product description

Danger
- The Emergency-Stop function must not be used as a substitute
for protective measures or other safety functions, but should be
designed as an additional protection measure.
- The Emergency-Stop function must not impair the effectiveness
of safety equipment or of equipment with other safety functions.
- The designer must ensure with a risk analysis that the emergen-
cy stop complies with the required safety category in combina-
tion with the control.
- When using emergency stops with key release the key must
only be inserted during the releasing procedure.
- In case of incorrect or unintended use or manipulation, the use
of the Emergency-Stop push-button does not exclude risks to
persons or damage to the machine or system components.
Please also observe the relevant information stipulated in
EN ISO 14119.
- An exceeding the electrical specifications of the Emergency-
Stop push-button (e.g. in the event of incorrect wiring or short-
circuits) may cause irreparable damage to the system.
