Based on the measured contact by a specified strength of the current relative to the increase of the temperature of the surrounding environment, and to determine whether it meets the safety norms.

INDUCTIVE LOAD: inductive load. A circuit is turned instant initial current when the current is less than the stability, and increase the form of slow load. When opening the contacts, the current is greater than the current stable work. The energy stored in the inductor will cause prolonged severe arc discharge. Inductive load, the current lags the voltage. The motor is the most common inductive load. Inductive load is the most troublesome of a circuit. See Resistive Load "," Capacitive Load. "

Logical level: The solid-state electronic circuitry (TTL, CMOS, etc.) using a low-energy relative level of value. Its low energy and does not cause the arc discharge, the softening or melting of the switch contacts. In such applications due to the arc discharge to perform self-cleaning of the contacts, generally require the use gold contacts to ensure the reliability of the switch.
