Frequently Asked Questions

Q: Is KCD1-105 the same as KCD1-101? A: Both are 2-pin SPST ON/OFF switches in the KCD1 family, but KCD1-105 has a round body specifically designed for circular panel cut-outs (⌀20mm), while KCD1-101 is rectangular.

Q: Can I use this switch for 12V DC circuits? A: Yes. While rated for AC use, this switch works perfectly for low-voltage DC circuits in automotive and hobbyist applications.

Q: What is the mounting hole size required? A: You need a ⌀20mm circular panel cut-out for snap-in installation.

Q: Is this switch suitable for 220V home wiring? A: This switch is rated for 6A/250VAC, making it suitable for low-load 220V applications. For heavy-load circuits, use a higher-rated switch like KCD4.
