HE6B Enabling Switches

3-position enabling switch with monitoring contacts. Smallest in its class.


  • Ergonomically-designed OFF-ON-OFF operation.
  • The switch does not turn ON while returning from position 3 (OFF) to position 1 (OFF)
  • IEC 60204-1 (2005), 10.9
  • IEC 60947-5-8 (2006), 7.1.9
  • Some teach pendants are equipped with two 3-position enabling switches, and when one switch is pressed to position 3 (OFF), the other switch must not enable machine operation even when pressed to position 2. Enabling of machine operation must resume after both switches are released. The monitoring switches monitor the OFF status of 3-position enabling switch, whether the button is returned to position 1 or the button is pressed to position 3 (monitor switches have direct opening action mechanism.)
  • Two contacts are provided in a 3-position enabling switch so that even if one contact fails due to welding or short circuit, the other contact can disable machine operation.
