Best for

Choosing an operating mode (Manual/Off/Auto, for example) right from a control panel's door, without depending on a screen or software — the same simple mechanical approach as the rest of this catalog.

  • 22mm Panel Mount
  • Maintained
  • ON-OFF-ON
  • 660V/10A

What is it and what's it for?

A panel selector is, mechanically, a rotary switch: you turn the knob and each position closes (or doesn't) different internal contacts. In this 'maintained' model the knob stays wherever you leave it, it doesn't spring back to center like a spring-return selector would.

Real-world use cases

At home

In a home panel this rarely shows up — it's more typical of equipment with several operating modes (a pump with manual/auto control, a gate with local/remote selection), not a simple lighting circuit.

In a business or workshop

In this catalog's VFD system guide, a selector like this on the panel door lets you choose between running the pump in Manual mode (the operator switches it on and off by hand) or Auto (the VFD/PLC decides based on the pressure sensor's signal), without having to open the panel or touch the internal wiring every time.

How to avoid buying the wrong one

  • It's maintained, not spring-return — if you need it to snap back to center on release, this isn't the right model.
  • 2NO means 2 normally-open contacts — the center position closes neither; check your starter/VFD's wiring diagram before deciding which position maps to which mode.
  • It's 22mm — the same mounting standard as the emergency stop button in this catalog, so they combine on the same panel door without adapters.

The investment takeaway

With 146 reviews and 4.6 stars, plus Amazon's Choice, it has a solid track record for a low-cost part ($14.99 for the pack of 2) — the real risk isn't component quality, it's wiring the position logic without checking it against the diagram of the equipment it will control first.

Waveshare RS232/485/422 to Ethernet Gateway (PoE)

RS485/ModbusPoEDIN rail
4.2 · 120 reviews

Supports all three serial standards (RS232/485/422) on one device, so it works for both old instruments with an RS232 port and multi-device RS485 buses. PoE power is a real plus in installations where there's no outlet near the panel — a single Ethernet cable carries both data and power. Confirm whether your Modbus master needs TCP Server or Client mode before buying; the mode is set in software, it doesn't come fixed from the factory.

#2MOLLOM VFD 1.5kW (2HP) — Single-Phase to Three-Phase 220V

MOLLOM VFD 1.5kW (2HP) — Single-Phase to Three-Phase 220V

220V 1P→3P2HPCNC
4.1 · 31 reviews

Single-phase input to 220V three-phase output — the typical choice for workshops without a three-phase feed that want to run a 3-phase motor. This is an entry-level model (2HP/1.5kW), meant for spindles and small CNC motors, not large industrial loads. The output range up to 3000Hz is only useful if your specific spindle takes advantage of it — for a standard 60Hz motor it's irrelevant.

#3VFD 4kW (5HP) Vector Control — 220V 1-Phase/3-Phase

VFD 4kW (5HP) Vector Control — 220V 1-Phase/3-Phase

Vector control5HP1P/3P
4.3 · 24 reviews

Has vector control (not just scalar V/F), which holds torque better at low RPM — important if you'll be threading or cutting at reduced speed. At 5HP/4kW it covers larger motors than the entry-level model, and accepts both single-phase and three-phase input, giving flexibility depending on the electrical setup available. Rated up to 26A — confirm your wiring and breakers can handle that current before installing.
