Rotary switches are used in numerous electrical applications to allow switching between circuits. The 51KMT30-01B11N is a popular rotary switch that is used in a range of applications, from commercial and industrial control panels to residential and automotive wiring. In this article, we will explore the application field and working principle of the 51KMT30-01B11N rotary switch.

Installation and Application Field

The 51KMT30-01B11N rotary switch is a multipole rotary switch. It is usually rated at up to 16A at 250V. This makes it suitable for a variety of applications including commercial and industrial control panels, residential and automotive wiring, and severe environment applications including weatherproof and flameproof applications. The quality construction of the switch mean it can be used in both indoor and outdoor applications.

The switch is easy to install and mount with a 0.18" (4.57mm) mounting hole size. It is also very compact, measuring just 2.9 x 1.49 x 2.53" (74 x 38 x 64.2mm). This makes it a great choice for applications where space is at a premium.

Working Principle

The 51KMT30-01B11N rotary switch works on the principle of momentary action. This means that when the knob is turned to the desired position, the contacts are made and power is transferred to the circuit. The contacts are then broken when the knob is turned to the next position. This makes the switch suitable for both momentary switch applications and applications where a switch needs to remain in a certain position.

The contacts of the switch are spring-loaded, which prevents arcing or sparking at the contacts. This prolongs the operational life of the switch, and it also helps to prevent damage to the contacts.

Conclusion

The 51KMT30-01B11N is a popular rotary switch. It is a multipole switch suitable for a variety of applications including commercial and industrial control panels, residential wiring, and severe environment applications. It is easy to install and mount and is very compact, making it ideal for space-constrained applications. The switch works on the principle of momentary action, with spring-loaded contacts to prevent arcing and sparking.
