Top 3 Customer Questions & Concerns ‍

1. Can this be used for DC applications?

   • Yes. While rated for 250V AC, these heavy-duty switches are excellent for 12V or 24V DC high-current systems in automotive and marine setups.

2. What size wire can the terminals handle?

   • The screw terminals are designed to accommodate ring or spade connectors, making them compatible with various wire gauges typically used in 15A circuits.

3. Does it come with mounting hardware?

   • Yes. It includes a threaded bushing with a hex nut and the "ON-ON" indicator plate to ensure a secure and professional-looking panel installation.
