Multicomp Pro MCNDP-04V 4-Pole DIP Switch, Piano Key, Red

The Multicomp Pro MCNDP-04V is a premium 4-pole DIP (Dual In-line Package) switch designed for precise configuration and control in a wide array of electronic circuits. Its distinctive red cover and piano key slide actuation offer a tactile and reliable switching mechanism, making it an excellent choice for applications where settings need to be manually set and securely held.

This SPST-NO (Single Pole Single Throw, Normally Open) switch is constructed from high-quality, flame-retardant materials. The lever, slider, and cover are made from UL 94V-0 rated thermoplastic PBT, ensuring excellent durability and safety. The switch base is constructed from robust PA66, also rated UL 94V-0. The internal contacts and terminals feature gold-plated copper alloy and brass, respectively, providing low contact resistance, reliable conductivity, and excellent resistance to corrosion for long-term performance.

With a contact rating of 25mA at 24V DC for switching and 100mA at 50V DC for non-switching applications, it is perfectly suited for low-voltage digital logic and signal routing. Its compact through-hole mounting design makes it easy to integrate onto printed circuit boards (PCBs).
