EAO release technical paper on emergency-stop switch design
06.01.2010
A new technical paper about the design and use of emergency-stop switches has been published by EAO – the expert partner for Human Machine Interfaces.
What designers need to know about emergency-stop switches, has been written to help product engineers and designers make the right choice in selection of emergency-stop switches for their machinery and equipment.
Mr DeJager Godert, EAO RnD chief, says: “Customers frequently ask what stop switch they should use? The answer is, it depends. Product developers must have a thorough knowledge of E-stop fundamentals, switch characteristics, and the international standards that apply to their industry.
“Not all stop switches and E-stops are the same, and different industries have different requirements. It’s important to know your industry.”
From one of the world’s largest ranges of switches, EAO offers three main types of stop switches: foolproof emergency-stops, foolproof stop switches and non-foolproof stop switches. Put simply, the difference between an “E-stop” and a “stop” is that E-stops offer the protection of foolproof actuation and conform to the relevant international norms and standards: EN IEC 60947-5-5, DIN EN ISO 13850 and EN 60204-1.
There is a vast range of options within these categories for switches that mount in 16 and 22.5mm cut-outs, including twist-to-unlock or key-to-unlock mechanisms, colored LED illumination, low-profile mounting styles and colors, – everything a product developer will need.
A very wide range of protective shrouds, enclosures, labels and other accessories are also available for all EAO stop products.
