Product Overview

The MW19 series is a 19mm mounting-hole metal anti-vandal pushbutton switch specifically designed for high-power industrial applications. It innovatively combines a solder-terminal base with an anti-vandal metal actuator head in a modular configuration, achieving a dual breakthrough of "high current carrying capacity" and "easy maintenance." Whether deployed in harsh outdoor environments or sophisticated industrial control cabinets, the MW19 delivers stable and reliable performance, providing precise control for your equipment.

Key Features

1. Current Carrying Capacity
Supports up to 26A/125VAC, far exceeding the typical 3–5A of standard 19mm pushbutton switches. This enables direct driving of high-power loads, eliminating the need for additional relays.

2. Modular Maintenance
The microswitch and actuator head can be replaced independently. In the event of a failure, there is no need for complete disassembly, improving maintenance efficiency by over 80%.

3. Environmental Adaptability
Panel‑side IP67 waterproof rating and IK08 impact resistance (stainless steel version) ensure reliable operation in harsh environments, including dust, moisture, and vibration.

4. Extended Service Life
Mechanical life reaches 1 million cycles for momentary versions and 500,000 cycles for latching versions, significantly reducing replacement frequency.

5. Flexible Customization
Choose from 2 housing materials, 7 LED colors, and 4 voltage ratings to meet diverse application requirements.
