Choosing a signaling indicator or operator control comes down to one question: what action or status do you need to communicate? On the shop floor, the difference between a basic button and a full control setup is not just wiring; it defines how an operator interacts with the equipment. The four options here span very different control styles, from a simple switch to a status tower with sound. Before you buy, think about where the control will live, what it will operate, and whether the operator needs to see, hear, or touch it.
Four very different control styles are covered here: a direct switch, a discrete button, a remote unit, and a signal tower. The one you need depends on the equipment you are wiring and how you want operators to interact with it.
The listed prices run from $14.29 to $395.00, with the pendant at the top of the range and the simple motor switch at the bottom.

3 Phase on off Push Button Switch, 220V/240V 30A Industrial Motor Starter Switch
The 3 Phase on/off Push Button Switch is the entry point for high-power switching. It is $14.29 with a push-button actuator, a three-way circuit type, and screw connectors. The brass contact material and normally open contact type match a motor starter switch role for 3-phase setups. It has no brand name attached, so judge it by the specs and condition. The main limitation is the modest feature set: it offers on/off control without the heavy-duty panel features or pendant convenience found in more expensive options. Choose it when you need a direct, economical switch for a 3-phase motor circuit at 220V/240V and up to 30A.
800T-A2D1 \"T\" ALLEN BRADLEY FLUSH HEAD BLACK PUSH BUTTON NIB NOS
The 800T-A2D1 \"T\" Allen Bradley Flush Head Black Push Button is new and heavy duty, and it costs $30.00. The flush mounting style and black button make it a straightforward choice for control equipment panels, commercial wiring, fan control, and industrial applications. It is priced per switch, and one unit was opened for pictures, so what you see is close to new-in-box. The model number 800T-A2D1 ties it to a specific push-button line, and the country of origin is the United States. The limitation is that you are buying a single push button, not a complete operator station or contact block arrangement, so the rest of the panel wiring is up to you.
Harrington NER2 4 button 2 speed pendant 13 foot cable with EStop & plug
The Harrington NER2 4 button 2 speed pendant with a 13 foot cable, EStop, and plug is the most expensive unit here at $395.00. It is a hoist remote with red and black buttons, cable mounting, and an on/off operation method, plus an emergency stop feature and pendant control. The condition is new open box. This is the only product in the group aimed specifically at overhead hoist or industrial equipment control. The limitation is its narrow scope: if you do not need a four-button, two-speed pendant with an emergency stop, you are paying for capability you will not use.
5-Stack USB LED Andon Tower Signal Light indicator Buzzer 5VDC Industrial Warn
The 5-Stack USB LED Andon Tower Signal Light with buzzer is a plug-and-play status indicator at $177.99. It runs on 5VDC from a USB cable, includes an 85 dB buzzer, a five-tier LED stack in red, yellow, green, blue, and white, and is meant for workstations, assembly lines, and CNC machine status alerts. The package carries a California Prop 65 warning. Unlike a power switch, this device is purely a signaling indicator, so it will not control motor loads. Choose it when you want to show machine or line status with light and sound and keep the wiring simple with USB.
For a basic power-switching install, the 3 Phase on off Push Button Switch is the low-priced path. For a straightforward button install, the 800T-A2D1 covers the button itself. For cabled remote control, the Harrington NER2 fits that role. For visible status alerts, the 5-Stack USB Andon Tower Light adds light and buzzer without high-voltage wiring.
