Rotary Switches

A rotary switch is an electrical switching device that utilizes a rotary motion of a shaft to operate the switch. They can be used to turn specific power on or off in a circuit. The 312-9E is a rotary switch that is small in size but can be applied in a variety of ways.

312-9E Application Field

The 312-9E is a compact type rotary switch with 1 pole 10 position and a maximum of 10A current rating, making it ideal for applications needing ruggedness, small form factor solutions, and reliability. It is an ideal switch for motor and appliance control, instrumentation applications, audio, industrial equipment, and lighting control.

It has a resistance of 6,000,000 cycles, a dielectric strength of 1.50KV and is rated IP40, making it suitable for harsh and networking environments. Additionally, it is flame retardant according to UL94V-0 standard and is certified by both UL and CSA.

312-9E Working Principle

The 312-9E is a basic device that works simply and effectively. A shaft is turned to select a contact appropriate for the desired application. The switch has two distinct parts—the rotor, which is connected to the shaft, and the stationary contact assembly. The number of positions determines the number of available output configurations for the switch.

As the shaft is rotated, the rotor makes contact with stationary contacts, completing the circuit between them. The switch can then be turned to the desired output settings and the power applied as needed. This process is repeated until all the desired settings are configured.

Aside from its practical applications, rotary switches offer a number of advantages over other electrical switching systems. These switches are reliable and simple to use, maintain and repair. The rotary switch is also very efficient and does not require any special tools or complicated set up processes.

Conclusion

The 312-9E is a small and reliable rotary switch that can be used in a variety of applications. It has a resistance of 6,000,000 cycles, a dielectric strength of 1.50KV, is rated IP40 and is flame retardant according to UL94V-0 standard. When used to its full potential, the 312-9E can provide a convenient and cost-effective solution for many electrical switching needs.
