This 22mm square head momentary piezo switch is made of premium SUS304 stainless steel, featuring excellent corrosion resistance and structural rigidity. It is equipped with IP68 waterproof/dustproof and optional IK69 anti-impact performance, working reliably in wet, dusty and collision-prone industrial and outdoor environments. Adopting momentary self-reset design, it is perfectly suitable for instantaneous signal triggering and jog control. With 2A rated current and 3-24V wide voltage compatibility, it adapts to most low-voltage control circuits. Dual wiring methods including prewired harness and welding terminals greatly improve installation flexibility. Gold and silver contacts ensure stable electrical conduction and long service life. The product supports a full set of customization on head shape, LED light, contact mode and shell size, and complies with RoHS and CE standards for global sales and projects. It has fast response, low power consumption and long service life, and can be matched with single-chip microcomputers to realize tapping trigger, music rhythm and lighting linkage functions, which is an ideal component for smart hardware development, electronic DIY and various industrial control devices.
