Changeover Switch

As the professional manufacturer, we would like to provide you Lixin Changeover Switch. This product has a wide range of uses and can replace switches in various countries. It can be used as circuit control switch, measuring equipment switch, motor control switch and main control switch, as well as welding machine switch. Comply with standards: The transfer switch used for main circuit switching and direct control complies with GB14048.3-2001 and IEC60947-3.

Here are some key features and functions of changeover switches:

Dual Input/Output: Changeover switches have multiple terminals or contacts for connecting two separate power sources or circuits. These inputs are typically labeled as "A" and "B" or "Source 1" and "Source 2."

Switching Mechanism: Changeover switches have a mechanism that allows the user to manually or automatically switch between the two input sources or circuits. The switching mechanism can be operated by a lever, knob, or motorized mechanism.

Functionality: Depending on the configuration, changeover switches can function as single-pole, double-throw (SPDT) or double-pole, double-throw (DPDT) switches. In an SPDT configuration, the switch can connect one common terminal to either of two other terminals. In a DPDT configuration, there are two common terminals and two sets of other terminals, allowing for simultaneous switching of two circuits.

Applications: Changeover switches find applications in various industries, including residential, commercial, industrial, and telecommunications. Common uses include switching between mains power and backup generators, transferring between utility and solar power sources, or selecting between different power phases.

Automatic Transfer Switches (ATS): Some changeover switches are equipped with automatic control mechanisms that detect power failures or voltage fluctuations and automatically switch to the backup power source. This feature is particularly useful in critical applications where uninterrupted power supply is essential, such as hospitals, data centers, and telecommunications infrastructure.

Safety Features: Changeover switches may include safety features such as interlocks to prevent simultaneous connection of both power sources, ensuring proper isolation and preventing damage to equipment or injury to personnel.

Construction: Changeover switches are built to high standards of durability and reliability, with rugged construction and high-quality materials to withstand the rigors of continuous operation in demanding environments.
