PBS-17A Screw Terminal Black Metal Push Button Switch

PBS-17A Screw Terminal Black Metal Push Button Switch

Matters needing attention

There are great differences between button and switch circuits in AC and DC circuits.
The control capacity of DC is very low. This is mainly because DC does not have zero points (zero-crossing points of current) like AC, so once the arc is produced it is difficult to eliminate and the arc takes a long time. And the current direction is unchanged, so there will be contact migration phenomenon, the contact will be unable to break due to uneven, may lead to misoperation.
The constant current and surge current of some types of load are quite different. It is required to be used within the allowable surge current range. The larger the inrush current, the greater the consumption and migration of the contacts, and the failure of the contacts can not be switched due to the fusion and migration of the contacts.
The higher the voltage, the greater the energy, and the greater the consumption and migration of the contacts.
