Presair DPDT latching air switch, center spout

This Presair air switch allows you to start and stop two spa devices (a massage pump and a blower for example), or to cut the live and neutral connections simultaneously on a single device.

Air buttons are rarely installed on new spas these days, as modern spas mostly have low-voltage digital controls. It works with an air button and some flexible tubing for air switches. It has a center spout.

Specifications
Electrical connections : 2 x 3 male spade connectors (2x1 input, 2x2 outputs)
Current rating : 21A per circuit (2 x 21A)

This DPDT switch can support two devices at the same time (these will be either on or off). Unlike the SPDT switch which will handle just one device at a time.
