Maybe someone can help me out here. I have tried looking all over for a push button switch that is 4 pronged and can turn on 2 separate devices at the same time. I need to be able to turn on a air pump and atomizer together. All the push buttons I have found only allow for 1 device. I am looking for push buttons that are from 10 - 20 mm. Thank you for any help to point me in the right direction.
