The screwless push-in spring termination accepts 18 AWG solid or ferruled stranded wire; the leg spring grips the conductor when pushed in and releases with a tool press on the orange actuator.
Wire termination uses a screwless leg-spring mechanism — strip the 18 AWG conductor, push it into the entry, and the spring clamps it. No screwdriver torque or re-torque needed. The vertical with board mating orientation means wires enter from the top, perpendicular to the PCB, which suits enclosure layouts where the board sits flat and wiring drops in from above.
