Comparison of some different switches. A miniature snap-action switch, also trademarked and frequently known as a micro switch or microswitch, is an electric switch that is actuated by very little physical force, through the use of a tipping-point mechanism, sometimes called an "over-center" mechanism.
Movement of the switch control lever applies tension to a spring until a tipping point is reached, and the contacts suddenly snap open or closed as the spring tension is released. As the power being switched increases, other methods are used to minimize or prevent arc formation. A plasma is hot and will rise due to convection air currents. The ...
A limit switch with a roller-lever operator; this is installed on a gate on a canal lock, and indicates the position of a gate to a control system A limit switch mounted on a moving part of a bridge In electrical engineering , a limit switch is a switch operated by the motion of a machine part or the presence of an object.
The devices had simple interruption and silver crossover, in some cases they were equipped with a snap mechanism. In Europe around 1940, the first cam switch from Ghielmetti, Solothurn / Switzerland, began to replace conventional roller switches. Switches could also be supplied as auxiliary current control switches with corresponding circuits.

"Try to see the good in people." "Come on − he can't be that bad." "You should be grateful to even be in a relationship." If you've heard these phrases before, chances are you've been bright sided.
Mercury switches are still used in electro-mechanical systems where physical orientation of actuators or rotors is a factor. They are also commonly used in vending machines and pinball tables , and used to be common in slot machines , for tilt alarms that detect when someone tries to rock or tilt the machine to make it vend a product or affect ...
