Over Current Trip Switch – Over Current Shutdown Relay
https://www.electronics-lab.com/project/over-current-trip-switch-over-current-shutdown-relay/
The project presented here is an over-current trip switch. It provides protection to a load when over current condition occurs. Basically, the project trips the relay when there is a short circuit or the load starts drawing much current. When the condition is favorable, press the tactile switch to power the load again. The threshold […]
Linear Actuator Controller with Limit Switch to prevent Overextension and Retraction
https://www.electronics-lab.com/project/linear-actuator-controller-with-limit-switch-to-prevent-overextension-and-retraction/
The project described here is a very useful device for use with linear actuators. This controller prevents the actuator from reaching the physical movement limits of the actuator, thus it prevents burnout of motor and physical/mechanical damage to the actuator itself to the mechanical machine associated with it. It also allows for a smoother stopping […]
