Board Layout and Wiring Fit
The screwless push-button clamp accepts 12-30 AWG; you push the button, insert the stripped wire, release. No screwdriver needed, no torque spec to check. The green nylon housing is keyed for visual identification on a multi-block board.
Ganging and Panel Fit
The side interlocking feature lets you snap multiple 1986712-2 blocks together into a continuous strip. A 4-position assembly uses two of these 2-position blocks side by side — no separate end cover required, and the interlock keeps the assembly rigid during wave solder. The single-level, through-hole mounting means one pass through the solder wave, and the 5.08 mm pitch matches standard terminal block footprints on 0.200" centers.
