Reliable Control and Signal Indication

The Liyond F10 Auxiliary Switch series is expertly engineered as an indispensable component within the control circuits of various high-voltage circuit breakers and isolating switches. Its fundamental working principle centers on a movable contact that precisely rotates via a square shaft at angles of 60°, 90°, or 120°. This precise motion ensures seamless contact or separation with the static contact, thereby reliably activating or deactivating controlled electrical circuits. Designed for direct drive, the auxiliary switch delivers the accurate control capabilities essential for robust and dependable system operation.

Enhanced Reliability Through Advanced Auxiliary Switch Design

The F10 auxiliary switch boasts adaptable structural forms, meticulously crafted to meet diverse application demands. The rotation angle of its central moving contact can be precisely adjusted to 60°, 90°, or 120°. Installation versatility is key, with F1 models offering both horizontal and vertical types. Furthermore, it provides distinct contact mechanisms: a fast mechanism for rapid response, and direct drive options with or without delay contacts. Specifically, the F10 series includes time delay contacts to compensate for anti-jump relay action lag, and instantaneous contacts designed to safeguard electronic components like counters from prolonged charging damage. This meticulous attention to detail significantly bolsters the switch's reliability and extends the service life of associated equipment.

Versatile Application in Demanding Industrial Environments

This Auxiliary Switch series finds broad application as an auxiliary electrical appliance. It is expertly designed for connecting or breaking signals to manage control, measurement, protection, and interlocking functions within the operating mechanisms of high-voltage circuit breakers, high-low isolation switches, low-pressure air switches, and low-pressure knife switches. The F10 series is also perfectly suited for integration into HV switchgear, capably functioning as an auxiliary switch in circuit breaker applications, or as a transfer switch or cubicle switch. Engineered for normal working environments, it performs consistently at altitudes up to 3000m, ambient temperatures ranging from -40°C to +40°C, and relative humidity averaging less than 95% daily and 90% monthly. Its robust design ensures reliable operation even with vibration acceleration up to 15m/s² and in environments free from dust, smoke, corrosive or flammable air, vapor, and salt fog.
