Product Overview

The HOSONG 19mm high-current non-illuminated push button is a high-load control switch for premium medium and high-power precision equipment. With a dedicated Φ19mm precision mounting hole, it perfectly fits compact high-end industrial controllers, energy storage devices and precision automation equipment. Balancing compact panel adaptability and high-current capacity, it adopts thickened anti-ablation composite contacts to enhance load resistance. The circuit-free structure delivers superior anti-interference, temperature and arc resistance. Reinforced anti-shake mechanical structure ensures zero clearance pressing and stable locking for strict precision equipment standards.
