Rotary switches have been used for decades as reliable and affordable control components in various applications. The RTAP31S12W25NS is no exception – being a single-pole, 12-position rotary switch, this component is an important part of modern electrical and electronic projects. Here, we will explore the RTAP31S12W25NS application field and working principle.

RTAP31S12W25NS application field
The RTAP31S12W25NS is designed to be used in applications where different circuits need to be connected in a quick and easy manner. Examples of such applications are motor control systems, audio and musical installations, measuring and test equipment, switching of loads in control panels, multi-step feedback and gain control systems, as well as many others.This rotary switch is suitable for both indoor and outdoor installations, as it is made from high-quality corrosion-resistant materials. It is also rated for 16A at 250VAC and 10A at 125VAC, making it suitable for a wide variety of applications. Moreover, the switch housing is designed to minimize the risk of physical damage in areas with high usage rate or other external hazards like dirt; it features a well-protected shaft and a fine-toothed ratchet mechanism.RTAP31S12W25NS working principle
The working principle behind this rotary switch is relatively simple – it allows for the selection of one of several circuits at any given time. It is based on the action of the central shaft, which is rotated to the desired position. When the switch is set to the required position, it enables connection between the contacts connected to the inner terminals of the switch – these are referred to as the ‘common terminal’.When the switch is set to a different position, the contacts connected to the outer terminals of the switch are enabled – these are referred to as the ‘associated terminal’. This enables the switching of different circuits.The central shaft is connected to the button on the top of the rotary switch, which allows for easy manipulation of the switch. The shaft is also equipped with a safety lock to prevent accidental movement of the switch.Finally, the RTAP31S12W25NS is composed of a series of AB-type contacts and arc suppressors, which enable reliable, long-lasting performance.Conclusion
In conclusion, the RTAP31S12W25NS is a high-quality, reliable rotary switch that can be used in a wide range of applications. Its working principle allows for the switching of different circuits with a single, simple action, while its construction offers excellent protection against physical damage and external hazards. Moreover, it is a cost-effective option for motor control systems and other similar applications.
