SY822 Conversion switch (for thermistor)Detailed product description：

The SY822 type transfer switch is a specialized switch for verifying thermal resistors, which is used in conjunction with a DC potentiometer or measuring bridge. It can connect five thermal resistors at a time, and each one is measured using a four terminal connection method. Switches can also be used for current commutation in electrical measurements.
