Product overview
Carling style rocker switches use a 21x37mm rectangular mounting footprint that is widely adopted in aftermarket marine and 4WD switch panels, consoles and housings. Many purpose-built switch panel enclosures are designed around this format, making the ACX1975BL a direct-fit replacement or addition in these panel types without modification. The Carling format is physically distinct from the 12mm round mount used by the ACX1971BL and ACX1973BL confirm your panel format before purchasing.
The blue LED illuminates when the switch is in the On position, providing clear status indication in low-light conditions. The third terminal powers the LED independently of the main switching circuit, allowing connection to a constant 12V or 24V supply. At 20A the ACX1975BL handles lighting and general accessory switching. For loads exceeding 20A, the switch should be used to trigger a relay.
