Pushbutton Switches: BB25AP-FC Application Field and Working Principle

Pushbutton switches are electrical control components used to open and close the electric circuit. They are widely used in all kinds of electrical control systems to control the start, stop and reset of all kinds of electric apparatus and electric equipment. BB25AP-FC is a special type of pushbutton switch designed for special application field and working principle.

Application Field

BB25AP-FC pushbutton switch is mainly applied for the general control systems like circuit breaker controlling system, energy conversion electronic apparatus and elevator control systems. It is suitable for having designs according to the customer\'s specific requirements for the switch button forms and electrical service life. Also, it is applicable to be operated by operating button(s) and convenient for opening and closing the electrical circuits. The switch is mainly composed of shell, fixed module, contact module, moving plate and an external spring gasket. The shell mainly provides the structure and shape of the pushbutton switch, and the contact modules acts as the contacts of the switch.The moving plate is connected to the contact module to open and close the contacts, and the external spring gaskets is used to add the pressing force and provides a certain flexibility to the switch.

Working Principle

BB25AP-FC pushbutton switch works on the principle of electrical contacts. It basically consist of two contacts which are open and closed depending upon the position of the switch. When in the OFF state, the contact is opened which interrupts the flow of current, whereas when in the ON state, the contacts are closed which allows for the current to flow uninterrupted.Apart from the regular open and close operation,BB25AP-FC switch provides other features like soft-start, thermal overload protection and adjustable time delay. Soft-start feature makes it possible for the switch to gradually increase its current instead of abrupt start which helps in avoiding surprises from the electrical system and makes it safer to use. Thermal overload protection feature helps in avoiding unnecessary heating of the switch due to excessive current under load. It also protects the switch from being damaged caused by the current fluctuation. The adjustable time delay feature helps in controlling the journey time of the switch by setting the time intervals, thus allowing users to control the distance between the switch and its contacts. All these features make theBB25AP-FC switch one of the most reliable and safe to use switch in its class.To conclude, BB25AP-FC is an advanced pushbutton switch which is specifically designed for special application field. It provides a variety of features like soft-start, thermal overload protection and adjustable time delay which makes it one of the most reliable and safe to use switch in its class. It is also suitable for having designs according to the customer\'s specific requirements for the switch button forms and electrical service life.
