This is a great selection of DIP switches, especially if you’re looking for smaller (fewer switch count per package) switches. Everything tested has worked. One came with a slightly bent pin but it wasn’t an issue, everything else was fine. These were a bit difficult to fit into the breadboard and the bigger packages didn’t seem to sit evenly, although the bottoms appear to be flush on the packages themselves. No issues fitting these into a PCB.Overall a choice kit for DIP switches.

This 41 Piece box of DIP switches by EGSCST has 10 values (or the quantity of switches per device). There are values from only 1 single switch up to the largest value of 10 switches on one single device. Their rating is at 24 Volts DC and 25mA (non-switched at 100mA). They are made of a durable plastic and metal with their soldering pins of 2.54mm pitch. Included in the kit are 5 each of the values 1 through 7 and then 2 each of the 8, 9, and 10 values. With these dip switches they are the basic slide up to on and back down for off. I really like a dip switch that you can really feel that throw action when you slide that tiny switch up into place, that makes me feel like there's the correct amount of tension as it pertains to the internal working contacts of each switch. Another simple feature included with this kit is the storage box they came in, it has 10 slots which allows the switches to be in their own valued section. And the plastic box itself is sturdy and has the dimensions of approx. 5.10inches long (130mm) x 3.62inches tall (92.1mm) x 0.73inch in thickness (18.6mm). However, I must say that the cardboard insert attached to the inside of the lid once it's opened does have a picture of the different values and the quantities of each, however it is not an accurate representation of how they are positioned according to their slots. Now it is entirely possible that EGSCST will correct this insert in the future and it's possible they may already have done so, but at the time of this review I have received one with a slightly different legend. This is a very, very minor issue and does not at all take away from the quality of the devices. I have only wanted it to be informative and relate my experience just so anyone does not think they have received the wrong item when they compare the insert with the way the dip switches are actually placed in the box. (That printed insert card has no bearing on whether my dip switches operate correctly only their location in a handy plastic storage box).I believe these dip switches are great for any project from just doing prototypes on a breadboard or PCB board, all the way up to finished and finalized projects. Although I have the kit in the red option, I believe it comes in Blue also.

I got these for Arduino projects. They are well made, basic DIP switches. This assortment includes a wide range of sizes from one to ten switches per module. Pin spacing is 2.54mm or 0.1 inch. My assortment was missing one of the 6-pin switches. These are basic DIP switches and they suit my purpose. I would buy these again.

These DIP switches are solidly constructed, have a nice solid click, a little indentation on each switch to make targeting one switch without slipping off, have nice silkscreened numbers/on identifiers, and is just right in terms of amount of force required to change the state. The legs are 4.1mm long. Spacing is great on printed boards and breadboards.However - the legs are only long enough two securely snap into one of the two kinds of breadboards I have. Looking at the other reviews with breadboards, I can see the commonality of style between those that work and those that do not. The attached image shows that the breadboard on the left is a secure fit, and the one on the right is not so great of a fit. If the manufacturer desires to claim solderless breadboard compatibility they should have given another mm on the legs here.

This EGSCST 41-piece DIP switch assortment has proven invaluable for my IoT prototyping work, particularly with ESP32 breadboard configurations. The comprehensive selection of switch positions (1 through 10) eliminates the frustration of not having the right configuration on hand when experimenting with different circuit designs.Core Performance & Features:The switches feature standard 2.54mm pitch spacing, making them perfectly compatible with breadboards and prototype PCBs. Each switch operates smoothly with a positive sliding action that provides clear tactile feedback between on/off positions. The red color makes it easy to spot switch positions at a glance, which is helpful when debugging circuits or documenting configurations.With a switching rating of 24V DC at 25mA and contact resistance of just 50mΩ, these switches handle typical microcontroller and IoT applications without issue. The 500MΩ insulation resistance ensures reliable isolation between positions, critical for maintaining signal integrity in sensitive digital circuits.Pros / Key Advantages:• Complete range from 1 to 10 positions covers virtually any configuration need• Standard 2.54mm pitch fits perfectly in breadboards and prototype boards• Smooth, reliable slide action with clear position indication• Low contact resistance (50mΩ) ensures minimal signal degradation• Organized storage box keeps different sizes sorted and accessible• Generous quantities (5 each for 1-7 positions, 2 each for 8-10)• Red color provides good visibility for quick configuration checks• Double-row design maximizes functionality in minimal board spaceCons / Areas for Improvement:The only minor limitation is the relatively low current rating (25mA switching), which means these are best suited for signal-level applications rather than power switching. For ESP32 and similar microcontroller projects where you're typically switching logic signals or configuration pins, this isn't an issue. However, those needing to switch higher currents will need to look elsewhere or add appropriate buffering.Value and Conclusion:For anyone involved in IoT development, microcontroller prototyping, or educational electronics, this DIP switch kit represents excellent value. The variety of positions included means you're prepared for everything from simple single-bit configuration to complex multi-bit addressing schemes.I've found these particularly useful for:Setting device IDs in multi-node IoT networksConfiguring ESP32 boot modes and peripheral optionsCreating selectable program modes in Arduino projectsEducational demonstrations of binary counting and addressingQuick hardware debugging by isolating circuit sectionsThe included storage case is a thoughtful touch that keeps everything organized in the parts drawer. At this price point, having a complete set of quality DIP switches on hand saves time and eliminates project delays waiting for the right part. Highly recommended for anyone's electronics prototyping toolkit.
