What is the difference between DC switch and AC switch2022-08-20
First, the arc extinguishing performance is different
1, DC switch: DC switch has no zero crossing, arc extinguishing can be very bad, so to add rated arc extinguishing installation.
2, AC switch: because the AC every cycle has a zero point, easy arc in the zero point.
Second, the installation situation is different
1, DC switch: in actual use, DC switch installed in the front of the electrical wire line.
2, alternating current switch: in actual use, alternating current switch is usually installed in the front of the electric appliances on the positive circuit.
Three. Different input voltages
1, DC switch: DC switch power input voltage is DC.
2, AC switch: AC switch power input voltage is AC.
