IDEC HE1G-L21SM Safety Interlock Switch, HE1G-L Series, SPST-NC, Screw, 125 V, 2.5 A, IP66

HE1G-L21SM is a grip style three-position enabling switch. The distinctive tactile feedback makes it easy to know the current position of the switch. Light operating force ideal for long-hour operation. The switch does not turn ON when being released from position 3 (OFF when pressed) to position 1 (OFF when released) (IEC 60204-1, 9.2.5.8). Two contacts are provided so that even if one contact fails due to welding or short-circuit, the other contact can disable machine operation. The distinctive tactile feedback when shifting to position 2 (enabling position) makes it easier to know where the enabling switch is currently positioned position 1 (OFF), 2 (ON), or 3 (OFF). Lighter operating force on position 2 assures more comfortable, stress-free operation when operating long hours.
