Question: Just based on available drawing and existing labels I am trying to figure out what connects with what. It is 2-button pendant.I think that red is common( +V) and black is ground.Any ideas based on below photohttps://i.ibb.co/bM6Gk3T7/circuit-pendant.png
Okay, let's analyze the image and try to deduce the wiring based on common practices and the limited clues.
Assumptions & Disclaimers
I am an AI and cannot guarantee the correctness of this advice. Electrical work can be dangerous. If you are not comfortable with this, consult a qualified electrician. Color codes can be inconsistent. While red is often used for positive voltage (+V) and black for ground, it's not universally guaranteed. Always verify if possible. We are only looking at the switch side. We don't know what the other end of these wires connects to (e.g., a motor controller, lights, etc.). That context is crucial for knowing what the buttons do.
Analysis of the Image
Wiring Observations
There are
four wires total coming into the pendant. Red and Black are grouped together: This suggests that they may be power in (possibly positive and negative or common) White and Orange are the remaining wires: These may be the output signals for the two buttons.2. Typical Pendant Operation
A two-button pendant often controls two separate functions (e.g., up/down, forward/reverse, on/off for two devices). Each button would likely activate its dedicated control signal.
Deduced Wiring Hypothesis
Based on the limited information and common conventions, here's the most likely scenario:
Red
Common/Power (+V). This is likely the positive voltage supply for the switch. Black
Ground/Return/Negative (-V). This is likely the common ground/negative voltage supply. Orange
Button 1 Output. When Button 1 is pressed, it connects the +V (Red) to this wire, sending a signal to the connected device. White
Button 2 Output. When Button 2 is pressed, it connects the +V (Red) to this wire, sending a signal to the connected device.
Important Considerations and Verification Steps (BEFORE applying power)
Continuity Testing (MOST IMPORTANT)
Use a multimeter to perform continuity tests. This is the safest and most reliable way to verify the wiring. With NO BUTTONS PRESSED: There should be no continuity (no connection) between the Red wire and either the Orange or White wires. Pressing Button 1 ONLY: You should have continuity between the Red and Orange wires. Pressing Button 2 ONLY: You should have continuity between the Red and White wires. No button should have continuity with black2.
Voltage Testing
If you know the voltage that should be supplied to this pendant, then confirm this BEFORE connecting any other components.3.
Look for a Diagram
Search for the model number or any identifying marks on the pendant itself. The manufacturer's diagram would be definitive.4.
Trace the Wires
If possible, carefully trace the wires back to their source and destination. This will give you more context.
To summarize, and to reiterate. The most important thing to do is to verify continuity. That is the only way you can be sure without applying power and potentially damaging the device. Flag for review
