An activation switch is an electromechanical device used to connect or break the flow of energy between other components within a lightsaber. Simple in design, it is as customizable as the other components that are used in the creation of a lightsaber. As such, a resourceful individual is capable of implementing unique features and designs into the switch that aids in their use of the powerful weapon.
The activation switch is part of a weapon that is an extension of the artisans' self. There are many options the creator can use to activate or deactivate their lightsaber. The most common option is the slide switch, as it is simple to use and if the lightsaber can be locked-on, the wielder can select the setting in a single motion. Pressure plates are commonly used as well though, as the name mentions, constant pressure needs to be applied in order to keep it activated. However, it does allow for one to switch their lightsaber on and off at a moment's notice as well as having the added safety of the blade shutting off should it leave the hands of the wielder. Other options include simple buttons and knobs to the rarest type of switch that allows only those that are capable of using the Force to activate.
The standard activation switch features a simple on and off function that allows the user to deactivate or activate the blade on demand. Sentient beings that wish for more functionality from their activation switch may include a setting that allows for the energy blade to be locked in the "on" position. It has been said that with a little imagination and skill the activation switch becomes one of the more useful parts of a lightsaber. Much like force-users themselves, the activation switch is an access point to an almost unlimited power source and can bring about unimaginable possibilities.
