Frequently Asked Questions
Q: What is the rated current and voltage for the KW11-3Z-2 microswitch?
A: The KW11-3Z-2 micro limit switch is rated for up to 5A and operates at low voltages — below 50V AC or 75V DC. This makes it suitable for a wide range of low-voltage electronics and automation applications, including 3D printers and CNC machines.
Q: How many terminals does the KW11-3Z-2 limit switch have, and how do I wire it?
A: The switch features 3 pins: COM (Common), NO (Normally Open), and NC (Normally Closed). For most endstop and limit switch applications, you will use COM and NC for a fail-safe normally-closed circuit, or COM and NO for a normally-open configuration, depending on your controller's requirements.
Q: Is this switch compatible with 3D printer endstops?
A: Yes! The KW11-3Z-2 roller lever microswitch is one of the most popular choices for 3D printer endstop switches (X, Y, and Z axis homing). Its compact PCB-mount footprint and standard 3-pin layout are compatible with most common 3D printer control boards, including RAMPS, SKR, and similar platforms.
Q: Why buy a 10-pack instead of individual switches?
A: Purchasing a 10-piece pack ensures you have replacement switches on hand for repairs, multi-axis builds, or prototyping. Microswitches can wear over time with heavy use, so having spares saves time and reduces project downtime. The pack also offers much better value per unit.
