Product Overview
The MW25 Series is a Φ25 mm high‑current metal pushbutton switch engineered specifically for high‑power circuit control, with "high power, high reliability, and strong protection" at its core. Available in two current ratings – 16A and 26A – it covers a broad range of power requirements, from industrial power equipment to heavy machinery. Featuring a stainless steel or aluminum alloy metal housing, combined with IP67 waterproof rating and IK08 impact resistance (for the stainless steel version), the switch maintains excellent electrical performance and mechanical strength even in harsh industrial environments. The innovative LED ring light and power‑symbol backlighting system allow operators to clearly identify the switch status under any lighting conditions. From CNC machine tools to new‑energy charging piles, the MW25 Series delivers reliable "press‑to‑actuate" performance, making it the preferred solution for high‑power human‑machine interaction scenarios.

Key Features
1. Dual High‑Current Ratings – One Platform Covers All Power‑Level Control Needs
16A Rating: 125/250VAC – ideal for medium‑to‑small motors, heaters, power distribution, and other conventional high‑power applications.
26A Rating: 125/250VAC – designed specifically for heavy machinery, high‑power inverters, industrial drying equipment, and other ultra‑high‑load scenarios.
Both ratings share the same mounting platform, allowing engineers to select the appropriate rating based on actual load requirements without redesigning panel cutouts or mounting structures.
2. IP67 + IK08 Dual Protection – Withstanding Harsh Environments
IP67 Protection: Completely dust‑tight and capable of withstanding temporary immersion in water up to 1 meter deep for 30 minutes – suitable for outdoor cabinets, food processing workshops, and high‑humidity industrial sites.
IK08 Impact Resistance (Stainless Steel Version): Withstands 5 joules of mechanical impact, effectively preventing vandalism and accidental damage – particularly well‑suited for public transportation, security equipment, and outdoor self‑service terminals.
3. One Million Mechanical Cycles – Uncompromised Performance Under High‑Frequency Operation
Momentary Type: 1,000,000 mechanical cycles
Latching Type: 500,000 mechanical cycles
On production lines with frequent start/stop cycles and high‑frequency test equipment, the MW25 series significantly reduces maintenance frequency and replacement costs with its extended service life.
4. Intelligent Illumination – Switch Status at a Glance
Two LED backlighting options are available:
Type E (Ring Light): A soft, uniform glowing ring around the button perimeter for clear status indication.
Type L (Ring Light + Power Symbol): The outer ring combined with a central power symbol, allowing quick status recognition even under bright or dim lighting.
Available in five single‑color LEDs (white, red, yellow, green, blue) and two dual‑color options (red+green, red+blue), with operating voltage covering the full range from 3V to 220V.
5. Quick‑Connect Terminals – Installation Efficiency Multiplied
#250 Quick‑Connect Terminal (26A‑specific): 6.3 mm standard tab, designed for high‑power wiring connections.
#187 Quick‑Connect Terminal (16A‑specific): 4.8 mm standard tab, compatible with general‑purpose connectors.
The solderless quick‑connect structure simplifies on‑site installation and subsequent maintenance, significantly shortening equipment assembly time.
Applications
Industrial Automation：
Spindle start/stop on CNC machine tools, hydraulic system control on injection molding machines, and emergency stop/start on production line conveyor belts – the 16A/26A ratings directly drive high‑power loads.
New Energy Equipment：
Start buttons on charging piles, grid‑connection switches on photovoltaic inverters, and main circuit control on energy storage systems – IP67 protection adapts to outdoor all‑weather environments.
Heavy Machinery：
Ignition switches on construction machinery, operating panels on port cranes, and power control on mining equipment – IK08 impact resistance withstands harsh working conditions.
Food Processing：
Start/stop control on large baking equipment, industrial dishwashers, and meat processing machinery – stainless steel housing complies with food hygiene standards.
Transportation：
Function buttons in train driver cabins, self‑service kiosks at bus stations, and ship control panels – high reliability meets safety‑critical application requirements.
Security Equipment：
Turnstile passage buttons, door release switches for access control systems, and trigger devices on alarm control panels – metal housing resists vandalism and physical abuse.
