Product Overview

The HOSONG 25mm annular illuminated push button is a large-aperture heavy-duty visual control switch with a rare standard Φ25mm mounting hole, designed for large-size panels of large automation equipment, heavy-duty units and large commercial devices. The oversized pressing area improves operation accuracy and blind operation efficiency for long-distance and extensive operation scenarios of large equipment. The panoramic annular soft LED light features a larger luminous area and longer visible distance for fast status identification during large-area workshop inspection. The thickened impact-resistant metal housing and sealed structure adapt to dusty and slightly oily heavy-duty working conditions, with durable contacts supporting auxiliary control of high-power loops for large equipment.
