Bob,



For a pitot heat relay would a P&B VF4 style 30amp  (Digikey PB687-ND) relay

be suitable or would a solid state relay such as Perihelion sells be better?



Thanks,



Stan Blanton

    In single engine aircraft, this device probably has

    the lowest operational duty cycle of any other

    accessory . . . no, second lowest. The baggage

    compartment light is lower.



    Some form of relay is useful because the popular

    toggle switches are not well suited to the peculiar

    warm-up current profile.



    The VF4 would be fine . . . as would any other

    device rated for this service.
