Multicomp Pro MCDHN-04F 4 Way SMD DIP Switch, 24V DC, 25mA

The Multicomp Pro MCDHN-04F-T-V is a compact, surface-mount DIP switch designed for high-reliability applications. Featuring a top tape sealed, half-pitch design, this 4-way switch is built to endure demanding industrial environments. It employs a robust construction with a black high-temperature thermoplastic nylon base and cover, paired with a white high-temperature thermoplastic LCP slide actuator, ensuring durability and stable operation across a wide temperature spectrum.

With a Single Pole, Single Throw (SPST) contact configuration, the switch offers a switching capacity of 25mA at 24V DC. It is engineered for precision and longevity, featuring gold-plated copper alloy contacts and gold-plated brass terminals to ensure excellent conductivity and minimal signal degradation over time. The operating force is a consistent 500gf, providing a firm, tactile feel during configuration changes.

This component is rated for an extensive operating temperature range from -40°C to +85°C, making it suitable for both extreme cold and heat. It boasts high electrical integrity, with a maximum initial contact resistance of 100mΩ and a minimum insulation resistance of 100MΩ at 500V DC. The switch is rated for a mechanical and electrical life of 1,000 cycles each, confirming its reliability for critical settings where frequent reconfiguration may be required.

Ideal for industrial automation, power management systems, and process control boards, this sealed SMD DIP switch provides a dependable solution for setting device addresses, configuring options, or selecting operational modes on printed circuit boards where space is at a premium and environmental sealing is necessary.
