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.
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.
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.

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 ...

A capacitive fixed-fixed beam RF MEMS switch, as shown in Fig. 1(a), is in essence a micro-machined capacitor with a moving top electrode, which is the beam. It is generally connected in shunt with the transmission line and used in X- to W-band (77 GHz and 94 GHz) RF MEMS components. An ohmic cantilever RF MEMS switch, as shown in Fig. 1(b), is ...
