3) The surge protection is the connection between the pressure sensitive resistance contacts, which is mainly to prevent the induction charge switch from being burned out by the arc, and the voltage sensitive resistor can be connected in parallel with the contact point, so that it can play a very good surge pulse absorption. In addition, the varistor can also provide fourth kinds of protection. This surge protection is mainly used for the protective connection of semiconductor devices. This connection is mainly used in silicon controlled, high-power transistor and other semiconductor devices. In practice, a parallel connection with a protective device is generally used to limit the voltage level below the protected device, which is an effective protection for semiconductor devices.
