HE2B Enabling Switch 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. • SufŢcient difference in operating force is provided for shifting from posi- tion 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- tion 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 Direct Opening Action disable machine operation. • The waterproof rubber boot provides IP65 protection.
