Quick Verdict
When you are deciding between signaling indicators operator controls for a workstation, you face a choice between two very different tools. The 3-Stack LED Andon Tower Light is built for continuous visual signaling; the 2NC 22mm Emergency Stop Push Button Switch is built for a fast, deliberate shutdown. Choose the tower light when you want to show a machine's state, and choose the emergency stop when you want to stop the machine itself.
Price and Feature Comparison
| Product | Listed Price | Price Signal | Primary Role |
|---|---|---|---|
| 3-Stack LED Andon Tower Light | USD 71.99 | Status display | |
| 2NC 22mm Emergency Stop Push Button Switch | USD 17.50 | Stop control |
The tower light is listed at $71.99, while the emergency stop is listed at $17.50, a $54.49 difference. That price gap reflects the tower light's additional components and signaling function, not a quality verdict on either product.
Where Each Product Wins
- The tower light wins when you need operators to see line status from a distance. It provides a steady flow of information through its stacked LED sections.
- The emergency stop switch wins when a worker must interrupt power fast. Its mushroom-shaped red button and push-twist action suit a rapid stop.
Product Notes
3-Stack LED Andon Tower Light

The Andon tower light is a complete status-light package. The red, yellow, and green LED stack can be set to off, on, or flash, giving you flexible status communication. It ships with a 120V-24V adapter, an ABB switch, and a 16-foot extension cable, which are useful pieces for a quick installation. The aluminum alloy pole, ABS housing, and PC lens point to a build intended for industrial environments. The trade-off is that it is a signaling light, not an emergency stop control. If an operator needs to interrupt power in a hurry, this tower light cannot perform that function. Also, the unit is listed as new open-box condition.
2NC 22mm Emergency Stop Push Button Switch

The emergency stop push button takes a different role. It is a latching push-twist switch with two normally closed contacts rated for 10 amps, so a simple twist resets it after a stop. The 22mm mounting hole and 40mm red mushroom button make it suitable for fitting into a control panel or enclosure. Screw terminals simplify wiring, and the listed operating voltage is 660 volts. Its limitation is that it gives you only one-way circuit control and no visual status indication. In a lean manufacturing setting, you would likely pair it with a tower light rather than replace the tower light with it. It provides a focused safety function, but it will not communicate a warning or normal state to the rest of the line.
Final Choice by Use Case
Choose the tower light when your main need is to show line status, direct operator attention, or support lean-manufacturing visual controls. Its stack of red, yellow, and green sections makes it a ready-to-mount signaling solution.
Choose the emergency stop switch when you need a compact latching stop control for a panel or machine. It serves a different purpose: stopping equipment quickly rather than signaling its state.
If your work area requires both functions, the two components work as complementary pairs in a single control strategy.
