Frequently Asked Questions

Q: What machines is this electromagnetic push button switch starter compatible with?

A: The KJD17/KLD28 series electromagnetic push button switch starter is compatible with a wide variety of machine tools including table saws, drill presses, band saws, lathes, grinders, and other workshop power equipment rated up to AC 250V / 18A (AC-1) or 15A (AC-3).

Q: What does the IP55 rating mean for this switch?

A: An IP55 rating means the switch is protected against dust ingress and low-pressure water jets from any direction. This makes it suitable for use in workshop environments where dust, sawdust, coolant splashes, or light moisture exposure are common.

Q: What is under-voltage protection and why is it important?

A: Under-voltage protection automatically cuts power to the machine if the supply voltage drops below a safe operating level. This prevents the machine from restarting unexpectedly after a power interruption, which is a critical safety feature in any workshop or industrial setting.

Q: Does this switch come in different pin configurations?

A: Yes. This electromagnetic push button switch starter is available with either a 4-pin or 5-pin configuration to suit different machine wiring setups. Please verify your machine's requirements before ordering. Note: color and pin variant are sent based on availability.
