Operating Principle

The RV16C-40-3 19F operates on the principle of contact-type impedance adjustment. At its core, it employs silver contacts; the high conductivity and excellent high-temperature resistance of silver significantly enhance the switch’s current-carrying capability, preventing contact fusion or oxidation failure under heavy currents. During operation, the component adjusts the effective resistance by modifying its length or cross-sectional area, thereby achieving current shunting or voltage division control to regulate current or voltage parameters in the circuit. This purely physical contact-based adjustment method eliminates the need for semiconductor inverters, allowing direct connection to high-power circuits for rapid response and stable precision while avoiding the heat generation and power loss issues associated with semiconductor components under high-power conditions.
