At some point in nearly every industrial controls build, you face a fork: do you need an e-stop button or a signal tower? Both are part of the signaling indicators and operator controls family, but they answer different questions. The first one stops equipment in an emergency; the second tells everyone in the area what is happening. Here's how the 2NC emergency stop push button and the ANDONT andon tower compare.
Quick verdict
For a direct, wired emergency-stop function at a single machine, the 22mm push button is the practical choice at $17.50. For production-floor visibility with multiple lights in one stack, the ANDONT andon tower is the more capable signal at $40.00. Your decision comes down to whether you want to cut power locally or broadcast status widely.
Comparison table
| Product | Price | Price bar | Best for |
|---|---|---|---|
| 2NC 22mm Emergency Stop Push Button | USD 17.50 | Stop control at the machine | |
| ANDONT 4-Stack Andon Tower Signal Light | USD 40.00 | Visible status signaling |
Where each product wins
- The e-stop push button wins when you need a latching, push-twist stop switch that wires into an existing circuit with screw terminals. It's the more compact, lower-priced control for an emergency stop point.
- The andon tower wins when you need multiple signal lights visible from a distance. Its tall aluminum pole makes it the stronger pick for floor-wide machine status.
Product notes
2NC 22mm Emergency Stop Push Button

This red mushroom switch is a direct safety-stop control for a 22mm panel cutout. Its latching push-twist operation means you press to stop and rotate to reset, while the 2NC contact set and screw terminals keep wiring simple inside an industrial control panel. The listed 10-amp rating and 660-volt operating voltage give it room for many power circuits, and the 40mm button surface is easy to hit in an emergency. The limitation is that it is a single-point control, not a visual signaling tower. It tells an operator at the machine that they have stopped it, but it does not broadcast status across a production floor. Choose this compact switch when your priority is a clear, wired emergency-stop function at one station.
ANDONT 4-Stack Andon Tower Signal Light

The ANDONT andon tower is built for visibility. Its aluminum pole supports a stack of light modules, so you can illuminate different states at once and see the signal from across a production line. It is listed for industrial automation and motion control systems, which means it is meant to communicate machine status in a busy environment rather than serve as an emergency-stop actuator. The sturdy aluminum pole gives the stack a stable, raised profile, but it does not add a push-button stop function. If operators need to be able to shut equipment down right where they stand, this tower should be paired with a separate e-stop switch. For high-visibility status signaling, the ANDONT tower is the more capable option.
Final choice by use case
If your setup is a single machine where an operator needs to cut power quickly, the 2NC emergency stop switch should be the starting point. If you are overseeing multiple machines or a longer line and need status to be readable at a glance, the ANDONT tower is the one to install. Neither control replaces the other; the right answer depends on whether you need to stop the process or signal it.
