The following are several common types of universal transfer switches

LW5 series: applicable to DC, AC 50Hz, voltage 500V and below circuits, can be used as the main circuit, electrical measuring instruments, such as change-over switches, etc., there are a variety of contact device gears such as 1~30 gears optional

LW6 series: Suitable for AC 50Hz, voltage 380V and below or DC 220V and below, current 5A and below AC/DC circuits, used for conversion of electrical control lines.

LW12-16 series: Suitable for AC 50 (or 60) Hz, voltage up to 380V and DC voltage up to 220V circuits, as a switch for master control or direct control of 3-phase cage induction motors of 5.5kW and below.

LW2 series: including general type, key type, signal lamp type, etc., suitable for different circuits and control requirements.

In addition, there are other series of universal transfer switches such as LW4, LW8, LW15, etc., as well as universal transfer switches on imported equipments, which are also widely utilized!
