AV4444 is a superminiature snap-action switch featuring a simulated roller lever actuator and straight PC board terminal configuration, designed for compact applications requiring reliable switching performance. The switch operates with a maximum operating force of 0.29 N and offers a mechanical life of at least 300,000 operations at 60 cycles per minute. It features silver-plated contacts rated for 0.5 A at 30 V DC, with an initial contact resistance of maximum 200 mO and insulation resistance of at least 100 MO. The device operates over an ambient temperature range of -25°C to +80°C and weighs approximately 0.2 g in its PC board terminal configuration. AV4444 is ideal for compact visual equipment such as cameras and portable VCRs, small-sized audio equipment, and office automation devices where space constraints and reliable switching are critical requirements.
