When you need a 360-degree rotary encoder with a push-to-actuate switch, two items can look exactly alike-same price, same D shaft, same mounting style. That is the case with these two EC11 encoders: both are listed at USD 2.50, and both share the same mechanical specs. So, what actually matters when the two choices are identical on paper? Here's a straight look at the details and the practical considerations.
Quick Verdict
If your project needs one rotary encoder, either of these units will serve the same purpose based on the listed specifications. Both feature a D-shaft actuator, through-hole PCB mount, 7-pin layout, 20 pulses per revolution, and a momentary push switch rated for 5V at 10mA. Neither outperforms the other in any listed attribute, so the decision comes down to which one you add to your cart first-or whether you order both to get matched units.
Specification Snapshot
| Feature | Both EC11 Encoders |
|---|---|
| Price | USD 2.50 |
| Actuator Type | Shaft (D shaft) |
| Mounting Type | Through Hole |
| Termination Type | PC Pin |
| Pulses per Revolution | 20 |
| Switch Type | Rotary encoder with push-to-actuate momentary switch |
| Package Contents | 1 piece encoder |
Where Each Encoder Wins
Neither encoder takes a lead in price, features, or specs because every listed detail is identical. The first EC11 encoder and the second EC11 encoder present the same D shaft, same mounting style, same 5V/10mA switch rating, and same $2.50 price. If anything, the advantage of having two identical units is for builds that need more than one encoder, such as dual-channel control panels or stereo preamp gain knobs.
Product Notes
1 Pc - EC11 360 Degree Rotary Encoder PCB Mount Push Switch D Shaft
This EC11 encoder matches what you see on the spec table: a D-shaft rotary encoder with a push-to-actuate momentary switch, designed for PCB mounting. At $2.50, it is a straightforward way to add a 20-pulse-per-revolution control to a project. The description also lists a 15 mm shaft length and 7 pins, which fits typical through-hole soldering. The main limitation is the package: it includes one encoder, so any knob, wiring, or enclosure hardware you need will have to be sourced separately.
1 Pc - EC11 360 Degree Rotary Encoder PCB Mount Push Switch D Shaft
This second EC11 encoder is indistinguishable from the first on every listed point: same D shaft, same through-hole mount, same PC pin termination, and the same $2.50 price. If you need two encoders for a build-say, left and right channel controls-this unit is a sensible second purchase. The catch is also the same: you get a single encoder, and the switch contacts are rated at 5V @ 10mA, so high-current switching would require additional circuitry.
Final Choice by Use Case
- Single encoder project: Either unit works. With identical specs and price, pick one and move on.
- Dual-control build: Grab both. You'll get two matched encoders for a total of $5.00.
- Prototyping and breadboarding: Either EC11 works with a standard PCB or breadboard, thanks to the through-hole pins and D-shaft actuator.
The bottom line: when two products match on every spec and price, the only real variable is your own order preference. For most buyers, that makes this an easy call-choose one or choose both.
