Abstract
A contact system in a low-voltage switch and a low-voltage switch are provided. The contact system comprises a bifurcated contact and a movable contact. The bifurcated contact has an upper bifurcated end and a lower bifurcated end. Electrical contact portions are respectively arranged on insides of the upper bifurcated end and the lower bifurcated end. Electrical contact portions are respectively arranged on upper and lower surfaces of an execution end of the movable contact corresponding to the electrical contact portions of the bifurcated contact. When the contact system is switched on and powered up, electrodynamic repulsion forces produced at the electrical contact portions of the bifurcated contact are offset, so that the contact system can stably maintain an ON state, thereby improving a short-time current withstand capability of a low-voltage switch using the contact system.
