📝 Description

The FS-V Vertical float switch is designed to facilitate liquid level sensing. These switches are specifically engineered to be fitted vertically on the top of tanks. Typically available in a Normally Open (NO) or Normally Closed (NC) form, horizontal float switches can work with different logic circuits.

Manufactured to stringent quality standards, this vertical float switch ensure robust performance even in demanding environments. They are capable of safely switching line voltages up to 30W, making them suitable for a wide range of industrial and commercial applications.

The design of this vertical float switch incorporates durable materials that withstand exposure to liquids over extended periods. By utilizing special engineering plastics as additional options, these switches can also offer resistance to corrosion and chemical degradation.

In practical applications, vertical float switches are employed in various industries, including wastewater management, food and beverage processing, and HVAC systems. Key features of horizontal float switches include their compact size, which facilitates easy installation in tight spaces or within existing equipment configurations.
