Submersible toggle switch ( IPx8 or better) or sealing solution

[MrMilbe]

Does anyone know where to get small switches (12V is fine) that are encapsulated and can be fully submerged in salt water? I had a couple of those aluminum marine push buttons that claimed IP68 but would fail fairly quickly.

It's actually for a surfboard project, not a boat, but its poly resin as well. I could also think of using a normal switch if its somehow possible to glass it in and protect it with some kind of membrane. But the material would have to be compatible with poly, which does not apply to any kind of rubber or nylon.

Or if anyone could point me to a heavy duty sealant that sticks to poly resin and rubber/nylon/tpu that would help as well.

Otto makes stainless IP68S and IP69k switches. they are available via newark electronics. they are about $34 each

Storm makes IP69k membrane switches (the company that made phone booth phone buttons and the call gate button arrays

however these are intended to have the connection side in an equally water-tight enclosure

if the switch is aluminum, it wont be IP anything for long in salt water.

True “water proof” switches (manual) are unicorns.

Ive not scene one that held up any length of time in my 40 years in the electronics industry.

Prox sensors are probably the most robust in adverse environments and easily encapsulated.... but not cheap.

What are you doing?
