Also known as high-inrush current switches, these switches can handle starting currents up to 10 times greater than their current rating, such as when a motor starts. They're often used with amplifiers, power supplies, and other high-starting-current devices.

Switches with an on-on position designation alternate power between sets of terminals.

Switches with a guard prevent accidental activation.

Submersible High-Starting-Current Rocker Switches

Rated IP67 for protection from dust and temporary submersion. Also known as high-inrush current switches, these switches can handle starting currents up to 10 times greater than their current rating, such as when a motor starts. They're often used with amplifiers, power supplies, and other high-starting-current devices.

High-Amp Outlet-Box-Mount Key Switches

Able to withstand high currents, these switches can be used with motors and pumps. They require a key to turn circuits on or off, limiting access to sensitive equipment. All are keyed alike, so they open with the same key.
