AT Series: The AT basic switch is the standard device in the AT family, capable of switching up to 3 amps at 28 VDC into resistive loads.
3AT Series: Higher ambient temperatures.
4AT Series: This device is designed to operate at temperatures lower than the standard AT switch.
10AT Series: This device is designed to operate at temperatures lower than the standard AT switch. Accordingly, this switch finds much use in space applications. For higher current capability than the standard AT switch.
