14-Circuit PCB Terminal Block, 5.08 mm Pitch, Push-Button Clamp
The 1-1986712-4: It terminates wires via a screwless push-button clamp — push the button, insert the stripped wire, release — no screwdriver needed. Rated 16 A at 300 V, it handles branch-circuit power in industrial control panels, HVAC equipment, and machinery junction boxes. The green polyamide housing follows the panel convention for ground/earth identification. Wire acceptance spans 12-30 AWG, covering both power feeds and signal-level sensor wiring in one block.
Push-Button Termination vs Screw Clamp
The 1-1986712-4 uses a push-button clamp instead of a traditional screw terminal. The button actuates a spring clamp that grips the conductor — no torque spec, no screwdriver bit, no risk of over-torquing a small terminal. For a 14-position block, that saves roughly 30 seconds per wire versus a screw clamp when you factor in tool pick-up and torque verification. The trade-off: the push-button clamp is less tolerant of fine-stranded wire below 24 AWG without a ferrule, but the 12-30 AWG range covers the common panel mix.
