Frequently Asked Questions
Q: What is the difference between the 20A and 32A versions of this rotary cam changeover switch?
A: Both versions are electrically and mechanically identical in form factor and function — the key difference is their maximum current rating. The 20A version suits lighter loads and smaller motors, while the 32A version handles heavier-duty 3-phase equipment and larger motors. Choose based on the full-load current of your application, and always size up if you are close to the limit.
Q: Can this LW26 rotary cam switch be used for motor forward/reverse control?
A: Yes. The 3-position (1-0-2) On-Off-On configuration is commonly used in motor control panels to switch between two circuit states — such as forward and reverse motor direction — with a centre-off position that safely disconnects the load. Ensure your wiring diagram matches the terminal layout before installation.
Q: What panel cutout size is required to mount this switch?
A: The body diameter is approximately 43mm, and the mounting hole diameter is 4mm. The face plate measures 50 × 50mm. Standard 40–45mm panel cutouts are typically compatible, but always verify your panel specifications against the product dimensions before installation.
