KP Series RGB Expansion

Product catalog summary

General Specifications
The KP Series RGB pushbuttons are designed for low-level electrical capacity with a maximum of 100mA at 12V DC. They feature a contact resistance of 200 milliohms maximum and an insulation resistance of 100 megohms minimum at 250V DC. The dielectric strength is 1,000V AC minimum between contacts and 1,500V AC minimum between contacts and case. Both mechanical and electrical life are rated at 5,000,000 operations minimum. The nominal operating force varies between models, with KP01 at 1.9N and KP02 at 1.6N. Travel distances also differ, with KP01 having a total travel of 4.5mm and KP02 having 3.5mm.

Materials & Finishes
The plunger and upper housing are made of polyacetal, while the lower housing is glass fiber reinforced PBT. Contacts are gold-plated stainless steel, and switch terminals are brass with tin plating.

Environmental Data
The operating temperature range is from -25°C to +50°C, with humidity tolerance of 90-95% for 240 hours at 40°C. The switches can withstand vibrations of 10-55Hz and shocks of 51G.

Installation & PCB Processing
Cap installation requires a maximum force of 50.0N. Soldering can be done via wave or manual methods, with specific temperature and time guidelines. The devices are not process sealed and should be cleaned with an alcohol-based solution.

Standards & Certifications
The lower housing meets UL94V-0 flammability standards, but the switches are not UL or CSA certified. They are intended for low-voltage, low-current logic-level circuits.

Distinctive Characteristics
The KP series offers a complete switch solution with RGB LED options, providing vibrant color combinations. The design includes tactile, nontactile, or tactile/audible actuation options, with a compact height of 23.0mm. The switches feature twin contacts with gold plating for high reliability and long life.

Ordering Information
The switches are available with various cap types, sizes, and colors, including flat, sculptured, and home key designs. The RGB LED specifications include maximum forward currents and voltages for red, green, and blue LEDs.

Assembly Instructions
The cap and plunger are designed for easy assembly and disassembly, with specific instructions for aligning and securing components. Electrostatic sensitivity precautions are advised during handling.
