22-mm Pushbuttons Sport IP65 Rating

Available with many options including illumination, the LB Series 22-mm, panel-sealed pushbutton switches are rated IP65 of IEC60529 for dust tightness and are protected from multi-directional water jets similar to NEMA 4 and 13. The IP65 rating is facilitated by an internal silicone rubber seal and a specially-designed external o-ring. The pushbuttons are available in SPDT, DPDT, momentary, and alternate-action configurations. The alternate-action models feature a latch-down mechanism to clearly indicate status. Other features and specs include gold or silver contacts, ratings of 3A at 125 Vac, 3A at 250 Vac, and 3A at 30 Vdc for power versions, 0.4 VA maximum at 28 Vac/dc for logic-level components, and a mechanical operating life of 1,000,000 operations minimum.
