Background

With the increase of the level of the electrical architecture of the commercial vehicle, the number of the control switches is increased. In general, control switches are classified into two main types, signal type and control type.

The signal type switch is mainly used for signal input and switching of the electric control unit, and logical control of a downstream electric control unit is performed through connecting/disconnecting an output voltage signal.

The control switch is mainly used for various derivative vehicle types such as engineering vehicles and modified vehicles. The switch is required to drive downstream power devices, such as various motors, heating resistors, pumps, and like loads. The required current is large. The conventional design schemes in existence are mainly divided into two schemes, namely a load type switch scheme and an external relay scheme.

Resulting in an inability to reduce the switch size. In the scheme of adopting the external relay, the installation position of the relay is limited (if the relay needs to be intensively installed with other relays, the relay needs to be fixed and the like), so that the connection wire harness is complex, the number of peripheral parts is increased, the reliability is reduced, and the cost is increased.
