Convex springs (i.e., barrel-shaped springs) have coils with larger diameters in the middle of the spring and coils with smaller diameters on both ends. This design allows the coils to fit within each other when the spring is compressed. Manufacturers use convex springs in applications that require more stability and resistance to surging as the springs decompress. Most applications that use them are in the automotive, furniture, and toy industries.

What is AC MCB?

Alternating current, also known as 60hz or 60 cycles per second, is what drives the power grid. The voltage alternates between +V and -V, changing 60 times per second. A voltage of 0 volts occurs 60 times per second at a certain point. The AC miniature circuit breaker will disconnect at this 0v point, extinguish the arc, and protect the circuit from excessive current.

There are many types of AC miniature circuit breakers on the market. However, the correct MCB should be selected according to the place of use.

Mid-back chairs offer fuller back support, and with the right ergonomic design, can be sat in for four hours at a time or longer.
