EMERGENCY-STOP SWITCHES WITH ILLUMINATED STATUS INDICATION ACTIVE/INACTIVE
SELF-MONITORING EMERGENCY-STOP CONTACT BLOCKS
The self-monitoring emergency-stop contact blocks developed by SCHLEGEL increase the safety. The functional principle: In case of a negligent assembly or a mechanical damage (separation of contact block from the actuator) the self-monitoring emergency-stop contact block ensures the immediate automatic activation of the emergency-off signal. The installation is switched off and can only be restarted after successful trouble-shooting.

FAQ
What is an emergency-stop button?
An emergency-stop button is a switch that puts a machine or a plant in a safe state in the event of danger. The emergency-stop button is locked after being actuated and the corresponding part of the machine or plant is shut down. Only after releasing the emergency-stop button the system can be started again.
What is an emergency shut-off button?
An emergency shut-off button is a switch through which machines or plants are cut off from the power supply in the event of danger. In contrast to an emergency-stop button the machine or plant is not being put in a safe state first, so the machine or plant can still pose a danger.
Which standards to be observed regarding emergency-stop buttons?
The machinery directive (2006/42/EG) requires for all machines to be equipped with at least one emergency-stop button. To ensure that an emergency-stop button can fulfil the requirements for a safe operation, it should be in accordance with the standards EN 60947-5-1, EN 60947-5-5 and DIN EN ISO 13850 and be tested according to TÜV or VDE.
What is a start-stop button?
A start-stop button has a similar operating principle as an emergency-stop button. Here the button will be locked as well after being actuated and can only be released by twisting or pulling. However, a start-stop button must not be used in a safety-relevant environment and thus may not have red/yellow colours.
What is a mushroom head?
A mushroom head has a similar design to an emergency-stop or start-stop button. In contrast to those buttons however, the mushroom head does not latch and only triggers a brief impulse. Mushroom heads are meant to be actuated quickly and safely, but they must not have the signal colours of red/yellow.
