Float switch SKF1A-5 T0-SKF1A-5

Float switches – reliable protection for installations

The SKF1A-5 float switch is a device used to automatically switch off equipment when the liquid level rises. Its design based on a float makes it ideal for use in pumping systems, tanks, septic tanks or wells. This device finds wide application both in domestic and industrial installations where it is necessary to maintain a safe liquid level.

Construction and principle of operation

The SKF1A-5 switch is equipped with a single-pole single-throw (SPST) switching contact (1CO), which means it has one normally open circuit. The elliptical, characteristic red casing provides good visibility and easy identification of the device. Thanks to the sealed housing (IP68), the switch is resistant to water and moisture, guaranteeing its reliable operation even in harsh environmental conditions. The float inside the housing reacts to changes in liquid level, moving up or down and activating or deactivating the switching contact.

Practical applications:

• Pump protection: Prevents the pump from running "dry", which could lead to damage.
• Liquid level control: Maintains the optimal liquid level in tanks and septic tanks.
• Process automation: Enables automatic control of devices based on liquid level.
• Alarm systems: Can be used to signal dangerously low or high liquid levels.

Key features and benefits

The SKF1A-5 float switch is a solid solution for demanding users. The rated current of 10A allows operation of most standard devices, and the rated voltage of 250V AC ensures compatibility with commonly used electrical installations. It is worth noting the high resistance to corrosion and mechanical damage – this translates into a long service life of the device and minimizes costs associated with its replacement. The simple construction facilitates installation and maintenance, and the versatility of application makes this switch an ideal choice for both professional installers and end users.
