Which are the waterproof tactile switches?
Waterproof tactile switches have an IP67 equivalent rating and also go by sealed switches.
Omron’s waterproof (IP67) tactile switch models are as follows:
B3W, B3S, B3SL, B3SN, B3SE, B3WN
Among models with a degree of protection equivalent to IP67, B3W/B3WN are through-hole type and the others are surface mount type. The types with ground terminal and gold plating are as follows:
- With ground terminal: B3W, B3S, B3SN
- With gold plating: B3SN

Although they have the sealing performance equivalent to that of IP67, please note that they cannot be used in an environment where water droplets stick constantly (for a long period of time).
