Multidirectional switch

The present invention relates to a multi-directional switch, and more particularly to a multi-directional switch that is thinner and that can increase the water-repellent prevention function.

According to the general multi-directional relationship, the elastic conductive rubber is pressed by the vertical or lateral pressing manipulation portion to bring the elastic conductive rubber into contact with the fixed conductive member, thereby achieving the closing of the circuit.
