Microswitches & Limit Switches

About

Microswitches & Limit Switches — SPDT Lever, Roller Ball, Endstop Modules Microswitches are snap-action switches with a precisely defined actuation point — the moment the lever travels the required distance, the contacts switch instantly with a crisp click. This makes them ideal for position detection, end-stop sensing, and limit switching in 3D printers, CNC machines, and robotic systems. This collection covers the full range of miniature microswitches and endstop modules available at Keszoox. Standard Lever Microswitches SPDT configuration — C (Common), NO (Normally Open), NC (Normally Closed) terminals 1A @ 125VAC — light-duty, for logic signal switching and low-current applications 2A @ 125VAC — medium-duty, for switching small loads directly 13mm lever, ~2mm travel — precise actuation point for position detection Pack of 5 Roller Ball Lever Microswitches 5A @ 250VAC — heavy-duty rating for direct load switching Roller ball tip — low-friction actuation by cams, ramps, and moving parts 16mm lever, ~4mm travel M2.5 mounting holes — for secure panel or bracket mounting Pack of 2 Endstop Switch Modules (3D Printer & CNC) Roller lever microswitch on PCB — standard 3D printer endstop format 3-pin header (GND / VCC / Signal) — direct connection to RAMPS, SKR, Creality, Prusa boards Compatible with all RepRap-based printers — Ender, Prusa, Creality, Voron SPDT Terminal Guide C (Common): Always connected — connect your signal or power here NC (Normally Closed): Connected to C when lever is NOT pressed — use for fail-safe circuits NO (Normally Open): Connects to C when lever IS pressed — use for standard detection Typical Applications 3D printer X/Y/Z endstops: Axis homing and travel limit detection CNC machine limits: Axis end-stop for routers, mills, and lathes Robot bumper: Collision detection for mobile robots Cam-operated switching: Timed switching by rotating cam Door / drawer position: Detect open/closed state Conveyor detection: Part presence and position
