The PV0H240SS-311 is a ring-illuminated pushbutton switch designed for panel-mount applications with a stainless steel housing and red LED illumination. It features a momentary contact configuration with a 2 A @ 36 VDC contact rating, 50 mO maximum contact resistance, and 100 MO insulation resistance at 500 VDC. The switch has a dielectric strength of 1,500 V RMS at 50 Hz and is rated for 200,000 electrical cycles with silver contact material and an LED base voltage of 1.8 V typical. Operating across -40°C to +85°C with IP67 ingress protection, it features an M12 × 0.75 thread mounting with a 12.00 mm panel cutout diameter and includes a hex nut and O-ring. This switch is ideal for industrial control panels, machinery interfaces, and applications requiring sealed, illuminated user feedback in harsh environments.
