SDA01H1SBD is a low-profile DIP switch from the SDA Series designed for compact switching applications requiring minimal board space. This single-position switch features an extended (H1) actuator for improved accessibility and surface mount gull-wing (S) terminals with gold-plated beryllium copper contacts (B) and no top tape seal (D). The switch is rated for 25 mA at 24 V DC or 100 mA at 5 V DC, with a contact resistance of 50 mO maximum and insulation resistance of 100 MO between terminals. It operates reliably over a temperature range of -40°C to +85°C with a mechanical and electrical life of 1,000 cycles at rated loads, and features a dielectric withstanding voltage of 300 V DC minimum for 1 minute. The SDA01H1SBD is ideal for address switching in industrial controls, logic switching in computers and peripherals, and function control applications where space constraints and reliable switching performance are critical.
