Abstract
A pushbutton switch includes a movable contact which effects an inverting motion in a case to get in and out of contact with a stationary contact to establish conduction and non-conduction of the switch. Grooves are provided along an inner bottom surface of the case so that free ends of the movable contact never scrape the inner bottom surface of the case upon an inverting motion of the movable contact.
