40PCS Double Row Dip Switch Assorted Kit Kulannder 2.54mm Red Switch

Description

Product Overview

The 40PCS Double Row Dip Switch Assorted Kit from Kulannder is a comprehensive collection of miniature toggle switches designed for a wide range of electronic projects. Each switch features a 2.54mm (0.1 inch) pitch, making it compatible with standard breadboard rows and PCB layouts. The kit includes five switches for each of the eight common configurations—1, 2, 3, 4, 6, 8, 10, and 12 positions—totaling 40 individual switches. Constructed from durable engineering plastic and a metal contact leaf, the switches deliver a non‑switching rating of 100 mA / 24 V DC and a switching rating of 25 mA / 24 V DC, with a contact resistance of just 50 mΩ and an insulation resistance of 500 MΩ at 500 V DC. The red toggle lever provides a clear visual cue for the on/off state, simplifying debugging and user interaction.

The kit arrives in a compact, reusable plastic storage box that keeps each switch safely separated and easy to locate. This organization is especially valuable for hobbyists, educators, and professionals who need quick access to specific switch types during prototyping or production runs. The package dimensions of 4.88 × 2.68 × 0.83 inches and a weight of only 0.35 oz make it convenient to ship, store, and transport.

Usage

These dip switches are ideal for a variety of applications where space‑saving, reliable on/off control is required. Common use cases include configuring address lines on microcontroller boards, setting mode selections on development kits, and creating user‑adjustable options on custom hardware. The 2.54mm pitch aligns perfectly with Arduino shields, Raspberry Pi HATs, and standard prototyping boards, allowing you to solder the switches directly onto a PCB or insert them into a breadboard for rapid testing.

In educational settings, the clear red lever makes it easy for students to understand binary settings and the impact of each switch position. For hobbyists building remote‑controlled devices, robotics, or IoT sensors, the kit provides the flexibility to experiment with multiple configurations without needing to purchase separate switch packs. The robust construction ensures the switches can endure repeated toggling, which is essential for projects that require frequent reconfiguration.

Because the switches are rated for up to 25 mA at 24 V, they can safely handle most low‑power logic circuits, LED drivers, and sensor interfaces. When higher current handling is needed, the switches can be used in conjunction with external driver transistors or MOSFETs, preserving the compact form factor while extending functionality.

FAQ

What is the maximum current each switch can handle?

Each dip switch is rated for a switching current of 25 mA at 24 V DC and a non‑switching current of 100 mA at 24 V DC, making them suitable for most low‑power logic circuits.

Can these switches be used on a solderless breadboard?

Yes, the 2.54mm (0.1 in) pitch is compatible with standard solderless breadboards, allowing you to insert the switches directly without soldering for quick testing.

Are the switches compatible with Arduino and Raspberry Pi projects?

Absolutely. The pitch and voltage ratings align with typical Arduino shields and Raspberry Pi HATs, and the red toggle lever makes it easy to set binary configurations for microcontroller code.

Do the switches require any special handling or orientation?

The switches are polarity‑agnostic for the toggle action, but for consistent labeling it is recommended to orient the lever upward when the switch is in the “on” position. The storage box includes labeled compartments to help keep each position type organized.

What warranty or support does Kulannder provide?

Kulannder offers a one‑year limited warranty covering manufacturing defects, and our technical support team is available to answer integration questions, provide datasheets, and assist with any troubleshooting needs.
