HE2B Double Three-position Enabling Switches
Multi-contact 3-position enabling switches Ideal for installing in large teach pendants
• Ergonomically-designed OFF-ON-OFF operation.
• Easy recognition of position 1 to 2 transition is made possible by a
snap action switch.
• Sufficient difference in operating force is provided for shifting from
posi t ion 2 to 3.
• Low pressure is required to maintain position 2, allowing for longtime
operation.
• Reliable operation is assured even when the edge of the operator
button is pressed.
• The switch does not turn ON while being released from position 3
(OFF) to position 1 (OFF) (IEC60204-1, 9.2.5.8).
• 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 posi t ion 2. Enabling of machine operation must resume after both
switches are released. For this purpose, also available are 3-position
enabling switches with monitoring switches for button returned to
position 1 and button 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.
• The waterproof rubber boot provides IP65 protection.
