Frequently Asked Questions
Q: Are these push button switches suitable for PCB surface-mount (SMT) applications?
A: Yes! These 4-pin tact switches support SMT-type mounting and can be directly soldered onto a PCB. Their standard footprint also allows output terminals to be used as jumper leads, giving you extra flexibility in circuit design.
Q: What is the operating voltage and current rating for these momentary switches?
A: Each switch is rated at 0.5A / 12V DC, with an EU LVD voltage classification of below 50V AC or 75V DC. They are well-suited for low-voltage consumer electronics, microcontroller projects, and DIY circuit boards.
Q: Are these tact switches truly waterproof?
A: These switches feature waterproof and heat-resistant construction, making them suitable for projects that may encounter moisture or elevated temperatures. Always verify the specific IP rating against your application requirements before installation.
