JESSINIE Keyboards Editorial Review

The 10Pcs 3x4 Matrix Array Membrane Switches have received a mixed reception from customers, particularly those involved in DIY electronics and home automation projects. Users appreciate the value offered by purchasing a pack of ten keypads for a relatively low cost, making them a popular choice for various projects. Customer feedback indicates that these switches perform adequately right out of the box when used with jumper wires, which is a plus for enthusiasts looking to integrate them easily into their setups. However, there are notable downsides highlighted in user reviews. Some customers have reported issues with key responsiveness, particularly that some keys stopped functioning after repeated use, which raises concerns about the durability of the product. Furthermore, the tactile feedback of the keys has been described as unsatisfactory—users have noted that the tactile domes lack adequate travel and feel overly mushy. Additionally, while the product's functionality is clear to those who are familiar with matrix keypads, there is a lack of detailed documentation on how to connect the switches effectively, which may be a barrier for novices. Some users have taken the initiative to provide their own guidance on pin connections, which showcases the community support among DIY enthusiasts but also points to a gap in the manufacturer's resources. Overall, the 10Pcs Membrane Switches serve their intended purpose for hobbyists and can be a cost-effective solution for those looking to enhance their electronic projects, although potential buyers should be mindful of the quality and responsiveness issues that may arise. **
