Abstract
The snap action switch has a spring biased plunger carrying directly or indirectly at least one articulated contact carrier extending laterally from opposite sides of the plunger and having two convex contacts of cylindrical, semi-circular or prism configuration. These contacts cooperate with stationary contacts arranged in pairs and including at least two pairs with a total of four contacts arranged in a near-rectangle; the contacts of each pair are inclined to each other for defining a trough-like configuration for concurrent engagement with one of the contacts on the carrier. This way, a total of four contact make and break points is defined for a single current path.
