The spring acts as an open or closed operation, pre-accumulates the spring force to the critical point, and instantly releases and quickly opens or jumps open the contact, so its operating speed is not affected by the hand operating speed. influences.

The arc-extinguishing device is an arc-extinguishing chamber that eliminates the spark generated by the operation of the internal contacts. Any contact that opens the load current will generate an arc (ie, a spark).

Because the arc itself is an electrical conductor that becomes a very high temperature air column, it uses the right-hand rule of Ampere to form a strong magnetic field between the iron plates of the arc extinguishing chamber. Air conductors quickly bend and stretch the arc, allowing the spark to extinguish more quickly.
