I wish comments on how to best achieve a design involving two limit switches on a DC motor, but which does not reverse the motor.
I've researched this design already on this forum; here's my work, I could not find an answer hence this post.
(and several related posts)
My design does not involve reversing a motor.
Operation of device: a programmable timer controls an AC power supply, AC2. A seperate AC source, AC1, powers a heat lamp controlled by a AC Thermostat. AC2, via a transformer, powers a DC motor. The DC motor has a shaft that always rotates clockwise, and an “arm” that contracts two “limit switches” (SIC: not sure if that’s the right term!) such that: (1) when Limit Switch 1 touches (brushes past) the DC motor Arm at point “A”, the power to the DC motor is cut (but the heat lamp continues to operate on its own circuit). Then, after a certain time, the DC motor is activated (powered on), by the programmable timer (or is there a better way?), and the DC motor shaft continues to rotate until the Arm touches Limit Switch 2, whereupon the power to the DC motor is cut for a certain predetermined time, and the process repeats. How to build this, using off-the-shelf components?
