If I am using a switch that is rated for 16A @125vac in a 12vdc application does the amp rating of the switch also change?

QUOTE(76-914 @ Feb 18 2011, 02:32 PM)  If I am using a switch that is rated for 16A @125vac in a 12vdc application does the amp rating of the switch also change? Use the DC rule of thumb: the highest AC amperage rating on the switch should work up to 30 VDC. In this case, the switch can probably handle 16A up to 30 VDC. But this depends on the switch...check the specifications if in doubt. |
