Frequently Asked Questions
Q: What is the difference between the KLD28 (4-Pin) and KLD28A (5-Pin) versions?
A: The KLD28 has 4 pins and is suitable for single-phase power tool applications, while the KLD28A has 5 pins to accommodate additional circuit connections, such as a neutral line or auxiliary contact. Check your existing switch's pin configuration before ordering to ensure a direct replacement fit.
Q: How does the under-voltage protection work on this switch?
A: The electromagnetic mechanism holds the switch contacts closed only while sufficient voltage is maintained. If the power supply drops below the operating threshold or cuts out entirely, the switch automatically releases and opens the circuit. This means the tool will not unexpectedly restart when power is restored, helping to keep operators safe in the workshop.
Q: Is this switch compatible with my bench saw or drill press?
A: Yes — the KLD28 / KLD28A is designed for use with a wide range of electric power tools and machine tool equipment rated at 250V / 16A or below, including bench saws, drill presses, lathes, and similar workshop machinery. Always verify your machine's voltage and current requirements match the switch rating before installation.
Q: Is the switch truly waterproof for outdoor or dusty workshop use?
A: The switch features a waterproof and dustproof housing that protects the internal contacts from moisture and fine particles such as sawdust. This makes it well-suited for demanding workshop environments. While it offers excellent protection during normal tool operation, it is not intended for full submersion in water.
