Abstract
The present invention discloses a wall switch with a current control safety module, includes a bottom seat, a triple-conductors assembly, a press-button assembly, a top cover, and a current control safety module. The current control safety module is structurally independent of other parts of the switch and operates via a fuse with a pre-set safety current threshold. The current control safety module makes an open circuit via a blown fuse when the current goes beyond the pre-set threshold.
