40MM Push Button Switch

40mm push button switch was Crafted from stainless steel or aluminum alloy, this metal push button switch features a 40mm diameter panel cut-out size for standardized panel integration and a sleek flat head actuator (non-illuminated) for intuitive operation. Its momentary function ensures circuit activation only during physical depression, resetting automatically when released—critical for precision control scenarios.

Engineered for durability, it boasts IP67 waterproof/dustproof rating and IK10 impact resistance to withstand harsh environments (rain, dust, vibration) and vandalism. Key electrical parameters include contact ratings up to 5A/250V AC, contact resistance ≤50mΩ, and insulation resistance ≥1000MΩ, ensuring stable current transmission. Mechanical life exceeds 1,000,000 cycles, with electrical life up to 500,000 cycles, supporting long-term heavy-duty use.

Ideal for industrial cabinets, elevator control systems, and access control panels where robust operation is required. It also serves in medical equipment (reset controls) and automotive/marine systems (horn or emergency buttons) due to its wide operating temperature range (-25℃ to +55℃). Certified by RoHS, CE, and TUV, it meets global safety standards for diverse markets.
