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.
Suffi cient 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-posi-
tion 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. •
