6P 3-Position Rocker Switch Overview == K4D

🧩 Terminology

Rocker Switch: A type of switch that rocks back and forth like a seesaw. Pressing one side causes the other to rise.
6P (6 Pin): The switch has 6 terminals (pins) for wiring.
3-Position: The switch has three selectable states, typically:
- ON - OFF - ON
- Position 1 - Center (OFF) - Position 2
- Or used for Forward - Stop - Reverse in motor control applications.

⚙️ Wiring Diagram (ON - OFF - ON Type)

┌────────┬────────┬────────┐ │ Pin 1 │ Pin 3 │ Pin 5 │ ← Common / Input ├────────┼────────┼────────┤ │ Pin 2 │ Pin 4 │ Pin 6 │ ← Output (depends on position) └────────┴────────┴────────┘

Position 1 (Left): Pin1 → Pin2, Pin3 → Pin4 connected
Center (OFF): All pins disconnected
Position 2 (Right): Pin1 → Pin6, Pin3 → Pin4 connected

Motor:     [ Pin 1 ]——Motor——[ Pin 2 ]
Power:     [ Pin 3 = +V ]    [ Pin 4 = –V ]
Bridges:   Pin1 = Pin6, Pin2 = Pin5 (internal)

🚦 Switch Behavior

Switch Position	Internal Connection	Motor Polarity	Motor Direction
Position 1	Pin 3 → Pin 1 (+)
	Pin 4 → Pin 2 (–)	+ to Motor A, – to B	Clockwise (CW)
Center (OFF)	No connection	Motor disconnected	Stopped
Position 2	Pin 3 → Pin 2 (+)
	Pin 4 → Pin 1 (–)	+ to Motor B, – to A	Counter-Clockwise

✅ Summary

This switch setup allows you to:

Toggle a DC motor forward/reverse
Stop the motor in the center OFF position
Use only 6 pins, no extra relays or logic
