This part is a Latching Style Single Pole Dual Throw Switch 20 Amp Hole Through Mount with 1/8" Spout air connector and the Wire connects are 5/16" male quick connect tabs and required panel hole is 5/8". Used in pools, spas, whirlpool baths, garbage disposals and many more.
This switch is the standard or Universal Replacement for most single Air Switches. It is a Normally Open Latching Closed Switch that operates when air is introduced to the diaphram via an Air Button and Tube.
This switch Generally fails for 2 reasons first an open in the actual electric part of the switch meaning when it is in the closed position electricity cannot flow through it to operate the attached pump or Blower, second when you apply air it doesn't latch or move to the closed position. Either way the switch needs to be replaced.
If you are replacing a latching air switch with only 2 terminals, just ignore the third terminal and connect to the two that are used on your old switch.
This switch has been used on many Spa Builders AP-4 and AP-1400, HydroQuip, Spa Babes SB1000, Len Gordon, Hercules, NuWave, ProPack and many more.
Note: These switches should only be replaced when the power is disconnected from your Hot Tub and by a Qualified Person who understand Electricity is dangerous and can Safely do the repair.
