Why Are Micro Switches Have Three Connection

This micro switch is a “relay contact type” микропереключатель. The relay has a Normal open NO and a Normal closed NC. Each contact corresponds to two terminals, то есть, four wires.

The switch here has 3 wires because the two contact power supplies are shared, and the other two wires, one is the usually Normal Open NO. The other is the ordinarily closed point NC.

Rated value: generally refers to the value that is used as a guarantee of the switching characteristics and performance, such as rated current, rated voltage, и т.п., on the premise of specific conditions (load type, Текущий, Напряжение, frequency, и т.п.).

Resin fixing (plastic-sealed terminal): After wiring, the terminal with a wire, fill the part with resin to fix the part and eliminate the exposed live part to improve the drip resistance.

Изоляционное сопротивление: refers to the resistance between non-connected terminals, между клеммами и незаряженными металлическими частями, and between terminals and ground.

Withstand voltage: The critical value that will not cause insulation damage after applying a high voltage for 1 minute at the specified measurement location.

G5D-900J05-V: It means the resistance of the contact part of the contract but generally the resistance value, including the spring and the conductor resistance of the terminal part.

Виброустойчивость: Misoperation vibration When the micro switch is in use, the contact is closed due to vibration does not separate within the specified time.

Impact resistance: Durable impact means that the micro switch will not be damaged by the mechanical impact during transportation or installation and meet the impact within the range of operating characteristics. Misoperation impact? Refers to the impact range where the contact closed due to impact and did not separate within a specified time when the micro switch is used.
