AV22PNA22 is a mushroom head security pushbutton switch featuring a combined NC+NO momentary contact configuration with a 22 mm bushing diameter. It offers a maximum current/voltage rating of 5A at 250VAC with resistive load, an initial contact resistance of 100 mO max, and insulation resistance of 1,000 MO min at 500VDC. The switch provides excellent durability with an electrical life of 1,000,000 cycles at 1A 250VAC and 50,000 cycles at full load, along with IP65 front panel sealing. Constructed with a polyester glass-filled case, silver/nickel alloy contacts, nickel-plated brass bushing, and anodized aluminum actuator, it operates reliably from -20°C to +55°C. This robust switch is ideal for security and anti-vandal applications requiring reliable performance and durability.
