How Is a Power Recliner Wired for Multiple Functions?

AI Thread Summary
Power recliners operate through a circuit with three states: raising the footrest, lowering it, and an off position. The switch functions as a two-pole, three-position crossover switch, which reverses polarity to control the motor's direction. The center position of the switch is off, while the momentary on positions activate the motor for raising or lowering. Diagrams illustrating this wiring have been shared to clarify the setup. Understanding this mechanism is essential for troubleshooting and repairs.

As far as I can tell there are three circuit states that control the recliner foot rest, raise it, lower it, and off. How is this wired, how does the switch function etc...? I assume the up and down switch flip the polarity across the motor, but that is all I can seem to reason out...

A cross-over switch.
A two pole switch, with three positions. (momentary on), off, (momentary on).
Centre is off. Cross-connect the two switches to reverse the polarity and direction.

Thank You!
 
We had that not so long ago, as I recall....

Oh, here it is o0)

I'm sure I blew it off thinking "When am I going to need that"!

I already made the diagrams to be sure I understand, but I see they match the other thread.

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
