Ultra Switches from Kar-Tech feature IP-68 sealing and are fully submersible. The switch uses an engineered silicone seal both between the top of the switch housing and the base, and again around the toggle actuator so that the switch itself, without need for a sealing boot, is completely sealed. The switches have an operating life of 2.5 million cycles and have an optimized internal structure and material for high cycle frequency.
