Mercury switch can be used in harsh conditions, it is robust. We can use it in extreme environments, i.e. steam, dust, oils, etc. Switching is done by tilting the switch. Mercury has very good electrically conductive properties. Contact resistance between the electrodes is less than 100 mOhm. It can be used, for example, as a vibration sensor.
