The boot is a very important part of the joystick, it helps protect the internal parts of the joystick from the environment, and also in many cases forms the panel seal. The level of IP rating will be heavily dependent on the choice of product and it’s boot. In the images shown here, there are two different types of boots, a ‘bowl’ style and ‘umbrella’ style. The ‘bowl’ style boot is best suited to internal applications where a low profile, aesthetically pleasing seal is desirable. The ‘umbrella’ style helps protect against water and particulate which may “rain” on the joystick, and is required to run off.
