Self-latching lumar button



The Self-latching lumar buttons are buttons added by RedLogic that glow in 16 different colors (see below). In contrast to the Lumar buttons and the Latchable lumar buttons, the Self-latching lumar buttons emit a continuous redstone signal if they are not activated. If the player presses them, the redstone signal is terminated and the button is locked. The player can unlock the button with a secondary redstone signal for example a Lever or Button on the same block (shown in Fig. 1).

With the Screwdriver and crouching the player can switch between following modes:
 * Default: If the button is activated, the light goes out.
 * Inverted: If the the button is activated, the light goes on.
 * Always on: The light is always on.
