Order specifications

Principle: It is a traditional mechanical switch, but with the addition of auxiliary contacts—equipped with resistors to suppress inrush current—alongside the main contacts.

Characteristics: Mature technology, low cost, and a simple circuit. However, switching operations generate mechanical noise; furthermore, due to the physical characteristics of mechanical contacts, true "zero-crossing switching" cannot be achieved, and the resulting inrush current impacts the lifespan of the capacitors.
