    Hi All

    I have been trying to find a small IP rated switch to suit my needs but its turning out to be harder than it should be.

    I have found this switch

    http://uk.farnell.com/apem/irr7z262/switch-nc-no-round-red-ip67/dp/1714213

    Can you tell me if it would be safe to use this switch within a 24V 10Amp circuit. The battery I use is a 24V Lifepo4 but when fully charged it is 29V. The unit drives a motor which at maximum power can draw 10Amps. It averages 1-2Amps though.

    I know this switch is rated at 5A but that is at 250V so would it be ok to use on my circuit.

    Thanks for looking

    Nothing in the specs suggests a higher current at a lower voltage, so I would recommend against using it for a current in excess of 5A.

    You could use the switch to operate a relay, or to turn on a mosfet though. (And in either case you could use a switch rated for a far lower current)
