{1003} How to Test BEKO Washing Machine Mode Selector Switch RS31-AA1AA-B with a Multimeter

Описание: In this video number {1003} How to Test BEKO Washing Machine Mode Selector Switch RS31-AA1AA-B with a Multimeter || Rotary Resistance Selector Explained. how to test beko washing machine mode selector switch RS31-AA1AA-B with a Multimeter || Rotary Resistance Selector or Rotary Decade Resistor Switch or Rotary Programmable Resistor or Rotary stepped resistor or Multi-step rotary potentiometer or Rotary resistor ladder switch or Resistor coded switch or Position-encoded rotary switch (resistive type)

In this video, we demonstrate how to test the BEKO washing machine mode selector switch RS31-AA1AA-B using a digital multimeter. This component is not a standard contact switch — it's a rotary resistance selector that works like a rotary decade resistor switch with 12 positions and a 1kΩ resistor ladder. Each position adds 1kΩ resistance, providing a programmable analog signal to the washing machine's control circuit.

We explain:

How to identify the terminals

How to measure the resistance steps

Why this switch is called a resistor-coded selector

Common names for this component in the electronics world

🛠 This switch is also known as:

Rotary Decade Resistor Switch

Rotary Programmable Resistor

Rotary Stepped Resistor

Multi-Step Rotary Potentiometer

Rotary Resistor Ladder Switch

Resistor-Coded Switch

Position-Encoded Rotary Switch (Resistive Type)

💡 These switches are used in various appliances for analog program selection, such as in BEKO washing machines and similar models.
