What is a radial lead vs axial lead for components like tact switches? Axial lead components have leads coming out of each end of a component, such as a capacitor, resistor or inductor.
Radial lead components, on the other hand, have leads coming out the same side. You might see this feature called out in electromechanical switches, primarily with through-hole tactile switches that feature radial lead packaging.
These tact switches are designed for an automatic assembly feed and high-density, high-speed PCB placement. The process allows for efficient, cost-effective application across popular markets like consumer electronics, telecommunications and industrial production.
With through-hole mounting and sealed ingress protection ratings, these tact switches offer unmatched dependability and usability at a low cost. Below, you’ll find E-Switch’s recently released TL6059 Series — an IP67 sealed tact switch with through hole mounting and radial lead packaging — as well as other tacts with radial leads.
