The SKQYABE010 is a pair of tactile switches manufactured by ALPS. They measure 6.1x3.7x2.5mm and weigh 260gf each. The switches feature a four-leg design, with two legs connected together to act as a common terminal. They are normally closed, meaning they are off until pressed. When pressed, the normally closed contact is made, connecting the two legs together. The switch is typically used in applications where an object needs to be pressed in order to activate a circuit. The tactile feel of the switch makes it useful for applications where a physical confirmation of the switch being pressed is needed.
