Micro switches—also known as snap-action switches—are compact electromechanical devices designed to open or close circuits when a specific force is applied to the actuator. Their quick action, reliability, and long service life have made them essential components in household appliances, control panels, safety devices, and industrial systems. Among the many micro switch models on the market, the DV16 Series stands out for its durability, compact design, and adaptability.
Manufactured by DEWO Electronics, the DV16 Series is engineered to deliver top-tier performance even in demanding environments. One of its most popular applications is in range hoods, where efficient ventilation, safety, and user experience are crucial. This article will explore the features, specifications, and applications of DV16 Series micro switches in range hoods, and provide guidance on choosing the right model for your needs.
The DV16 Series is a versatile line of micro switches designed to operate reliably under harsh conditions such as heat, moisture, vibration, and contamination—common challenges in kitchen environments. With a compact size and robust construction, these switches can be seamlessly integrated into space-constrained designs without compromising performance.
Key strengths of the DV16 Series include:
High reliability
Compact form factor
Flexible actuator options
Wide electrical rating range
Long mechanical life
These features make DV16 micro switches especially suitable for modern range hoods that require precise, responsive, and durable control components.
Range hoods rely on micro switches for accurate and safe operation. In a typical kitchen ventilation system, the DV16 Series performs several essential functions:
DV16 micro switches activate or deactivate the fan when the user presses a button or opens/closes a panel. Because these switches respond instantly, they enable the fan to operate exactly when required, ensuring efficient smoke and odor extraction.
Many range hoods integrate lighting to illuminate the cooking area. DV16 switches ensure the lights turn on or off smoothly and reliably with user commands or preset operations.
Advanced models may use DV16 switches in multi-speed systems. With precise force sensitivity, they allow for accurate speed adjustments to match different cooking intensities.
DV16 switches can work in conjunction with heat, smoke, or airflow sensors. This allows the hood to:
Shut down automatically during malfunction,
Increase fan speed when excess heat or steam is detected,
Prevent overheating accidents.
As kitchens move toward smart appliances, DV16 switches can be paired with microcontrollers and sensors to enable:
Automatic fan activation,
Humidity or temperature control,
Timer functionality.
To understand why the DV16 Series performs exceptionally well in range hoods, it’s important to look at its physical and technical characteristics.

DV16 Series micro switches enhance range hood functionality in several ways:
The quick-action mechanism ensures instant fan activation, maintaining clean air and reducing cooking odors.
From tactile push buttons to smart panels, DV16 switches support seamless, user-friendly operation.
Automatic shutoff, overheat protection, and sensor-triggered responses improve appliance safety and user confidence.
Whether used in traditional mechanical hoods or modern smart kitchen systems, the DV16’s compatibility and versatility make it a preferred choice for manufacturers.
Selecting the correct model ensures optimal performance and long-term durability. Here is a simple checklist:
Identify:
Control type (manual, automatic, sensor-based)
Electrical load (voltage & current)
Actuator style needed
Installation space constraints
Compare models based on:
Electrical ratings
Mechanical life
Actuator variations
IP rating
Mounting configuration
Choose a switch that meets or exceeds your range hood's specifications.
Confirm that the chosen DV16 micro switch fits your existing circuit design and mechanical layout.
Real-world feedback can help you evaluate durability and performance across different models.
Select a supplier or manufacturer offering strong support and warranty coverage for added peace of mind.
