Rotary Gear Limit Switch Working Principle

Electromechanical limit switches use arms levers knobs plungers or other actuators that make physical contact with another object.

Rotary gear limit switch working principle.

The device works through a gear transmission drives a cam system operates on 4 or 6 microswitches that after a certain number of revolutions predispose the engine or equipment at startup or at the stop. Drive mechanisms are classified into three types as shown in the following figure. Multi pole multi position rotary switches are mostly used to switch operating conditions. Custom input ratios are available on request.

The actuator is the part of the switch which physically comes in contact with the target. Springer controls offers rotary limit switches with input ratios from 1 1 to 8100 1. The main function of the limit switch is to open or close an electric circuit when the physical limit of the operation of the controlled device has reached. The working principle of the rotary switch is.

Structures and principles drive mechanism of limit switch the drive mechanism of the limit switch is an important part of the limit switch and is directly linked to seal performance and operating characteristics. Rotary limit switches rotary limit switches are electromechanical controls consisting of an input shaft gear reducer signal transmitter and limit or safety switches. The push button is actuated by hand whereas the limit switch is operated mechanically. Rotary limit switches may use mechanical or solid state means to detect an object and switch a load.

Most limit switches contain the following functional parts in one form or another. Limit switch working principle the limit switch is like a 1 no 1 nc push button. This is the switch. In some limit switches the actuator is attached to an operating head which translates a rotary.

They can be configured with up to 12 contacts for signaling and combined with other accessories like encoders and potentiometers to achieve your desired result. Single pole single position rotary switches are often used together with rotary potentiometers in operation.
