The transfer switches market has been valued at USD 1.6 billion in 2023 and is likely to grow steadily with a CAGR of 7% by 2033. A transfer switch is an important mechanism that safely connects or disconnects different electrical sources from an electric load. Most of the residential spaces and businesses always have standby generators during power outages. Also, many businesses and college campuses generate their own electricity on site but use the local grid for some of their electricity. Transfer switches prevent electricity backfeed onto the electric grid, such as from a private generator into a house, for safe and effective power management.

Transfer switches are devices that transfer critical load connections essentially between the primary and backup electrical power sources. When the regular power source fails, many facilities turn to emergency power sources like generators or backup utility feeds; transfer switches automate this process without human involvement for many facilities, including data centers, factories, hospitals, and other vital infrastructures.

Increasing demand from the power and transmission industries, along with supportive government policies and extensive reforms for integration into renewable sources of energy, is boosting the sales of transfer switches. Segmentation of transfer switches can be done in automatic and manual categories. Automatic transfer switches dominate the market presently by virtue of higher reliability and faster response at the time of failure.

In 2019, ABB launched its OTM series of small automatic transfer switches in China. The OTM series of power source automatic switching is used to ensure a safe and reliable electricity supply to grid terminal loads in residential and commercial buildings, fire safety systems, manufacturing, data centers, etc.

Transfer switches are also segmented based on transition modes: open, closed, delayed, and soft load. An open transition transfer switch makes contact with one power source before breaking contact with the other. Differently, closed transition transfer switches are connected to a new power source before being disconnected from the current one. This is suitable for applications where there can be no interruption to the power supply. A delayed transition transfer switch breaks contact with one source and then briefly pauses before connecting to the alternate source. A soft transfer transition switch synchronizes generator power with utility power before transitioning between sources.
