The SKRTLAE010 tactile switch is a 4.46x3.5x3.3mm, 160gf switch manufactured by ALPS. This switching technology is based on physical contact and works with electrical currents, allowing for concave paddles which make it easier to operate with just a touch. Additionally, the guide bosses ensure that the contact is precise and there is no risk of contact wear or misalignment. The 160gf rating means that it has an actuation force of 160g meaning the switch takes a slightly higher actuation force than some of the other types of switches on the market. This makes it ideal for applications where more force is needed to operate the switch.
