Rotary Code Switches in Circuit Breakers?

Rotary code switches are widely used in intelligent circuit breakers. Because circuit breakers are used in a wide range of applications, and the actual application of the equipment to be protected varies, this requires intelligent circuit breakers to have different gears, for which several rotary code switches may be required on a circuit breaker. The principle of its implementation is actually relatively simple, generally a low-level signal is connected to the common pin of the knob, and the other pins are connected to the microcontroller through pull-up resistors. When the rotary switch to turn the pin and the common pin on, the pin on the high and low level becomes low, so the microcontroller will know the position of the rotary switch at this time. For different positions, the microcontroller can realize different setting values.

    The promotion of rotary code switch on the circuit breaker

    1. Must be intelligent circuit breakers, general circuit breakers do not use.

    2. Some intelligent circuit breaker manufacturers do not necessarily produce accessories intelligent control parts, commissioned by professional intelligent control parts production.

    3.7 * 7 push handle, need to assess the opening of the mold.

    4. Generally an intelligent circuit breaker if useful to the rotary code switch, generally will apply 6-8.
