The MMC60 Switch is a cost-effective accessibility switch, an assistive device used by people with physical disabilities to control electronics (e.g. phones, computers, adapted toys,  game controls, etc.).

This switch is ideal for people who have difficulty with fine motor control. The flexure in the design allows the user to press, hit, or smash on the switch with a high degree of force.

The top button / activation surface is attached to the base by threading it on. This makes it easy to change tops to change color, labels, etc.
