what is the working principal of this limit switch? Generally we use it in limiting travel of a door, Traditional…
Relay Working Animation shows the operation of relay visually. The NO & NC contacts of relay will change on giving…
Principle of Flow Switch - It uses “paddles” as a flow-sensing element which actuates switch contacts to identify the required…
A temperature switch is one detecting the temperature of some substance. Temperature switches often use bimetallic strips as the temperature-sensing…
Yet another style of electronic level switch uses ultrasonic sound waves to detect the presence of process material (either solid…
A more primitive variation on the theme of a “tuning fork” level switch is the rotating paddle switch, used to…
Tuning Fork Level Switch uses a metal tuning fork structure to detect the presence of a liquid or solid (powder…
Some level switches use a float to sense the level of a liquid surface, actuating an electrical switch by the…
Another electronic liquid level switch technology is capacitive: Sensing level by changes in electrical capacitance between the switch and the…
A pressure switch is one detecting the presence of fluid pressure. Pressure switches often use diaphragms or bellows as the…
