Describing mechanically operated switches
A mechanically operated switch is controlled automatically by factors such as pressure, position, or temperature. This differs from a manually operated switch, which is operated by hand or by a human operator. They are used in situations where automatic control is required. The switch operates automatically by pressure, temperature, or position via a mechanism in the switch. They can also be referred to as sensors.
A mechanically operated switch takes the place of a human operator. Some examples of this type of switch are as follows:
- Limit switch
- Level switch
- Pressure switch
- Temperature switch
Let’s have a look at each.
Limit switches
This is a switch that is operated by the motion of a machine part. It operates when a predetermined limit is reached. The standard limit switch is a mechanical device that uses physical contact to detect the presence or absence of an object. It consists of a switch body, an actuator, and an operating head...
