PRODUCT CENTER
The DV Double Micro Switch is a compact, high-precision electrical switch designed to deliver reliable dual-circuit control within a single housing. By integrating two independent switching mechanisms in one unit, this switch allows simultaneous or sequential control of two separate circuits, making it ideal for applications that demand redundant safety, dual-position detection, or multi-functional operation.
DV Double Micro Switches are widely used in industrial automation, machinery, household appliances, automotive systems, and limit control applications where space-saving design and reliable performance are essential. Built with robust materials and precision snap-action mechanisms, they offer excellent repeatability, long electrical life, and high resistance to environmental factors.
Like a standard micro switch, the DV Double Micro Switch uses a snap-action mechanism to change the electrical state rapidly with minimal actuator movement. Inside the housing, two sets of contacts operate independently, each triggered by the actuator or a common lever. When the actuator reaches a specified operating force, the contacts ‘snap’ from one position to another, ensuring quick break/make actions with excellent repeatability and minimal contact bounce.
This dual configuration allows the switch to:
Control two independent circuits at the same time
Provide redundant switching for safety-critical functions
The detection of multiple positions or states can be achieved through a single switch component.
