HE series enabling switch providing 3 position “dead-man handle” functionality
The IDEC enabling switch series (HE series) are ergonomically designed to work where there is a human and machine interaction and this human interaction is required to turn on the machine or robot while the user is in a potentially dangerous area.
Typically the enabling switch (HExB) is mounted into grip switch (see the HE1G & HE2G series below) or is used within a robot pendant or machine control station. The 3-position enabling switch not only turns on a machine when pressed, but also turns the machine off when “over pressed” (squeezed) or released – providing the switch is installed correctly with an adequate safety circuit.
Two contacts are provided so that even if one contact fails, the other can disable the machine operation. Functionally they meet all the stringent requirements for IEC standard 60947-5-8 for this type of product.
