Main Parameters Of The Switch

Dec 18, 2018

Rated voltage: refers to the safety voltage allowed when the switch is operating normally.

The voltage added to both ends of the switch is greater than this value, which causes a fire breakdown between two contacts.

Rated current: The maximum safe current allowed to pass when the switch is connected, and when this value is exceeded, the contact point of the switch burns because the current is too large.

Insulation Resistance: Refers to the conductor part of the switch and the insulation part of the resistance value, insulation resistance value should be above 100mω.

Contact Resistance: refers to the resistance value of the switch between each pair of contacts in the open state. General requirements below 0.1-0.5ω, the smaller the value, the better.

Pressure resistance: refers to the maximum voltage that a switch can withstand between a conductor and a ground. Life: Refers to the number of times the switch can operate under normal operating conditions. General requirements in about 5000-35000 times.
