Air plunger to operate push button spa units,
spa pool/bath, insinkerator operators
Top is 44mm dia(1.72")
Low price, low profile, white and just push in
a 34.44 mm (1.356")hole in the spa combing
(or deck, fence, anywhere you can make a hole and route air tube)
Air switches also available
for spas, Insinkaerators, any where you don't want your wet hands touching electric switches
or some low cost remote control is desired, up to 3 mtr.
If your hole is too big, cut a plastic or stainless washer and glue,
if too small just file out with a wood rasp
and glue with a little silicone.
Some old buttons had a nut underneath, just cut the top off, ( use wide wood chisel if plastic)
push in the hole, then fish out the air tube with a coat hanger, fit the new button.
If metal button, grind top off with your 4" disc, carefully!
I have done this many times on spa baths and pools,
need help? call Bob 0243690299, text 0408053048
