Rotary Switches
A rotary switch is an electrical switch with multiple positions, which are selected by rotating the switch to align the desired input terminal with the output lead. The Model 54A02112N-A01104N is a 4-pole 12-position rotary switch. It allows for single or multiple switching applications and is designed primarily for low current needs involving AC/DC low voltage control.
The 54A02112N-A01104N is a precision rotary switch with a long life and high reliability. It is made up of a molded housing and has a resistance of 10 kilo-ohm (KΩ). The contacts are silver-plated, which gives it superior electrical properties. The switch features a rotational travel of 250 degrees, a maximum current rating of 5 ampere (A) and an operating temperature range from 0 to 85 degrees Celsius (C).
Application Field
The 54A02112N-A01104N rotary switch has a wide range of applications in industrial, commercial, and residential settings. It can be used to control and regulate electrical circuits in home and automotive appliances, as well as commercial equipment such as cash registers, vending machines, and point-of sale systems. It is also suitable for low-voltage lighting control, power and data distribution, and many other applications.It is especially suited for use in circuit boards where a single component could control multiple connections. This saves space and simplifies the design while reducing the cost of the product.Working Principle
The 54A02112N-A01104N rotary switch works using a cammed actuator that rotates with the switches positions. The cammed actuator is attached to the stem of the switch and is located in the center of the switch body. This actuator has several slots that allow the switch contacts to move from one position to the next as the actuator is rotated.The switch is opened when the cammed actuator is rotated to the neutral position. The cammed actuator is then used to select any one of the positions. As the actuator is rotated, the cam slot causes the switch contacts to move to that position. The switch contacts are designed in such a way that they hold the switch in the selected position even after the external force has been removed. This ensures that the selected position remains stable and the switch is not accidentally switched to a different position when the actuator is rotated through the cam slots.Conclusion
The Model 54A02112N-A01104N rotary switch is a highly reliable and durable product that offers superior electrical performance. It is suitable for both commercial and residential applications and is easy to install and configure. The switch works using a cammed actuator that rotates with the switches positions and can be used to control multiple connections from a single component, saving time, space and cost.
