Two industrial controls, two different ways to stop equipment. You can add a compact 22mm emergency stop push button to a machine, or you can buy a complete handheld pendant assembly for remote operation. Both put a stop button within easy reach and both are intended for industrial use, but they solve different problems. One works as a single component you wire into an enclosure; the other is a ready-to-use control station with cable and plug. The real question is whether you need a fixed e-stop component or a movable operator control.
Quick verdict
The 22mm Emergency Stop Push Button is the right component when your job is a straightforward fixed stop control. The Harrington NER2 is the right system when the control needs to move with the operator.

Where each product wins
The 22mm emergency stop wins on simplicity. It is a single switch, so there is nothing to assemble, and installation is direct. The switch holds the stop until someone resets it. If you are adding one emergency stop to a control panel, this is the straightforward route.
The Harrington NER2 wins on completeness and portability. Instead of a loose button, you receive a pendant ready for remote operation. All of the controls are built into the handheld station, so the operator does not have to walk back to a fixed panel to change settings. For equipment that is controlled from a handheld position, the pendant is the more practical package.
Product notes
22mm Emergency Stop Push Button
This switch is built for one task: giving equipment a latching emergency stop you can twist to reset. The mushroom actuator is easy to spot, the push-twist action holds the stop until it is rotated back, and the 2NC contacts are rated 10A at 660V. Screw terminals make wiring direct, and the 22mm mount hole fits a common industrial cutout while the overall size stays small. The limitation is that this is only a single switch. There is no cable, no plug, and no extra buttons for directional or speed control. If your operation relies on a handheld pendant with multiple functions, this one-button component will not replace it.
Harrington NER2 4-Button Pendant
The Harrington NER2 is a different kind of operator control: a complete pendant assembly rather than an individual switch. It combines four buttons, two speeds, a 13-foot cable, EStop, and plug in one unit. The on/off operation keeps the controls straightforward, and the cable mounting style lets an operator hold the station while moving around equipment. The trade-off is that it is a complete kit, so you are buying the cable, plug, housing, and buttons as one package rather than adding a single pushbutton to an existing panel. For a job that only calls for one emergency stop, this pendant is more control than the situation needs.
Final choice by use case
- For a single emergency stop on a panel: Choose the 22mm Emergency Stop Push Button. Its latching red actuator and 22mm mount hole make it a direct fit for adding one stop control.
- For a hoist-style handheld operation: Choose the Harrington NER2. The pendant is ready for remote control, so the operator can stay near the load instead of reaching for a fixed panel switch.
