How to choose the best limit switch for shapeoko
Start from contacts, not the housing
The contact layout decides what the switch can switch. The TWTADE pick gives NC plus NO as a DPDT layout, while the HiLetgo, Joinfworld and Baomain BM-3104 picks give SPDT layouts and the Baomain WLCA12 pick gives a double-break 1NO plus 1NC layout. A DPDT layout suits wiring two circuits from one actuator, while an SPDT layout suits a single circuit with a changeover contact. Check the contact layout against the controller input before ordering.
Sealing and wiring
Sealing runs from IP65 on the TWTADE pick to IP66 on the WLCA12 pick and IP67 on the Joinfworld and BM-3104 picks, while the HiLetgo pick states no sealing figure. Wiring differs just as much: the BM-3104 pick arrives with a 3m pre-wired cable, the Joinfworld pick arrives with 300 mm leads, the HiLetgo pick uses wire leads, and the TWTADE pick uses screw terminals. Pre-wired leads save soldering, while screw terminals suit builders who want to choose their own wire.
| Switch | Contacts | Sealing |
|---|---|---|
| HiLetgo V-156-1C25 | SPDT | Not stated |
| TWTADE ME-8108 | NC + NO DPDT | IP65 |
| Baomain WLCA12-2-Q | 1NO + 1NC | IP66 |
| Baomain BM-3104 | SPDT 1NO + 1NC | IP67 |
| Joinfworld WS1-Z5 | SPDT 1NO + 1NC | IP67 |
Pack count and spares
Pack counts run from single switches to a 10-pack. The HiLetgo pick ships 10 switches, the TWTADE pick ships 4, the Joinfworld pick ships 2, and the two Baomain picks ship 1 each. A multi-switch pack suits a full set of axis limits plus spares, while a single heavy-duty switch suits one replacement.

Project Match
- CNC homing and limits: the TWTADE, WLCA12, Joinfworld and BM-3104 picks state CNC use; the HiLetgo pick states voltage and current ranges instead.
- Dusty or damp shop corners: the IP67 picks (Joinfworld, BM-3104) and the IP66 WLCA12 pick state sealed housings.
- Tight mounts: the HiLetgo micro switch states a 3mm button height and 3.2mm fixing holes.
- Replacement on a single axis: either Baomain single switch, with the WLCA12 pick giving a double-break circuit and the BM-3104 pick giving a pre-wired cable.
How the scores add up
The HQ Score weighs performance, build, value, safety and warranty. For a limit switch, safety means stated listings and sealing: the HiLetgo pick states UL and cULus, the TWTADE pick states IEC and IP65, and the other picks state IP66 or IP67 housings. None of the five picks state a warranty term. How we pick explains the weights.
