Searching for a budget ip67 momentary switch for my caving light

Hi all
I am building a caving light using a handmade host.
I am searching for a momentary switch that need to be:

  1. Reliable
  2. ip67 waterproof or better (possibly by using a boot)
  3. mudproof (possibly by using a boot)
  4. About 16mm diameter

For my previous light I used APEM ISR3SAD300 which is:

  1. Cost more than a compete Convoy S2+
  2. Get stuck in muddy caves

The mud problem can be solved by using a sealing boot but is cost 10$ for a simple silicone boot :(

Any recommendation for a cheaper (but still reliable) switch?

I’ve used this one: https://www.newark.com/c-k-components/k12c12-5n/switch-1mm-travel-2-5n-ip67-seal/dp/58T4766
It’s 12x12mm though. It worked well but note that I didn’t use it for very long before I decided I wanted a lighted switch instead. I haven’t used any other IP67 rated switch.

It is strange, the switch is sealed but it is connected to the body only by clips, no thread and no O-ring

I didn’t care about that. I just wanted the actual switch to be rated, I took care of the sealing to the flashlight body myself with epoxy.
