Rotary switches are used in electrical engineering and the most common type of switch used in domestic and industrial applications. The 412-9T2E rotary switch is a switch that is operated by a rotating knob mounted on a mounting block secured by two screws. The 412-9T2E is typically used to switch high voltage and/or high current. It features an internal aluminum frame construction and is UL listed.

A 412-9T2E rotary switch provides nine switch positions and a total of two switch positions. It is designed for indoor mounting and each switch position has a separate contact. This feature allows for up to 18 switch actions for difficult switching applications. There are seven independent contacts, each rated for 30A at 600 volts, enabling it to handle higher amp loads and higher voltages.

When it comes to installation, the 412-9T2E rotary switch is easy to install. It is typically mounted on the outside of an enclosure or panel in an accessible location. The two mounting screws are spaced 2” apart and must be secured to the mounting block before installation. The installation instructions also require that the nuts and washers that come with the switch are used to secure the mounting block. Once installed, the rotary switch can then be turned to the desired position and locked into place by tightening the Locknut.

The 412-9T2E rotary switch is an electrically operated switching device, and it works on the principle of the break-before-make contact system. This means that when the switch is operated, the contacts close before the previously energized contacts open. This gives it the advantage of eliminating electrical arcing which can be a hazard to sensitive electronics. It is also designed with a fail-safe function, which means that in the event of a loss of power, the switch will automatically open and break the connection.

The 412-9T2E rotary switch is a versatile, high performance, and highly reliable switching technology. It is suitable for all kinds of applications, such as motor control, lighting, HVAC, power distribution, and many other areas. It is also easy to install and maintain, and the switch is the perfect choice for any switch needing the highest level of reliability and safety.
