MD-S700C explosion-proof shell type pressure switch
Equipped with explosion-proof shell, all metal shell MD-S700
Product details

The MD-S700C series pressure switch is a pressure switch that causes micro switch action due to pure mechanical deformation. When force is applied to the pressure sensing component, it deforms and moves upward. Through mechanical structures such as railing springs, the micro switch at the upper end is activated to output electrical signals.
The MD-S700C series pressure switch is made of stainless steel metal shell and pressure sensing film. Its characteristics are easy to use, stable operation, and long mechanical life. Users can set control points through the accessory tools provided with the product, or request our factory to pre-set pressure control points at the factory.
The MD-S700C series products are widely used, especially suitable for pressure control and protection of automation equipment, mining machinery and other application machinery.
