Metal Momentary Push Button Switch

The 40mm cut-out size metal momentary push button switch emerges as a high-reliability option in the realm of metal push button switches, combining standardized installation, rugged metal construction, and precise momentary operation to address diverse control needs of push button switches across industries. As a professional metal switch, it stands out for its adaptability and durability.

Crafted from high-grade 304 stainless steel or nickel-plated brass, this switch features a robust housing that resists scratches, corrosion, and mechanical impact—critical for long-term use in harsh environments. Its defining 40mm cut-out size adheres to industrial panel standards, enabling seamless integration into control cabinets, equipment dashboards, and operation panels without the need for custom modifications, greatly simplifying installation workflows.

The momentary function is its key advantage: the switch closes the circuit only when pressed, and automatically resets to the open state once the pressure is released. This ensures precise one-time control, avoiding misoperation caused by persistent activation. Electrically, it supports a rated current of 3A-5A and voltage of 12V-250V AC/DC, with contact resistance ≤50mΩ and insulation resistance ≥1000MΩ, guaranteeing stable current transmission. Mechanically, it boasts a service life of over 500,000 cycles, meeting the high-frequency use demands of industrial sites.

This metal push button switch is widely used in industrial automation (machine start/stop), elevator control (call buttons), and commercial equipment (vending machine operation). It fills the gap between standard push button switches and specialized metal switches, becoming a go-to choice for scenarios requiring both standardized installation and reliable momentary control
