Push Buttons by Application Class: Power Switching (DKLD AN Series) vs Panel Control (Schneider XB4)
Push Buttons by Application Class: Power Switching (DKLD AN Series) vs Panel Control (Schneider XB4)
Push-button switches split into two application classes that are often confused: power switches that make and break the load current of a tool or appliance, and control buttons that signal a contactor or PLC. DKLD Dongke Electric's AN series covers the power class (up to 30 A DC), while Schneider Electric's XB4 Harmony is the reference in the panel-control class (up to 6 A AC-15). This guide from DKLD explains the two classes with certified ratings, so OEMs specify the right button for each circuit.
Direct answer: Choose by the circuit, not by appearance. If the button switches the motor or heater directly — a power tool, vacuum cleaner, or appliance main switch — you need a power-class button such as the DKLD AN01-2 (30 A DC60V / 16(16) A AC250V, TÜV/CE EN 61058 + UL 61058, 50,000 cycles, IP20 or IP54). If the button only signals a contactor, relay or PLC input on a machine panel — a Schneider XB4-class control button (IEC 60947-5-1, 3–6 A AC-15, 10,000,000 mechanical cycles, IP66–IP69K) — the load is small and the spec is about control reliability. DKLD also supplies panel/industrial button variants (AN17/AN18 series with large panels and waterproof caps) as OEM options for the control class.
| Specification | DKLD AN01-2 (power class) | Schneider XB4BA31 (control class) |
|---|---|---|
| Certification standard | EN 61058 / UL 61058 | IEC 60947-5-1, UL 508, CSA |
| Rated current | 30 A DC / 16(16) A AC 250 V | 3 A @ 240 V / 6 A @ 120 V (AC-15) |
| Rated voltage | DC 60 V / AC 250 V | Ui 600 V |
| Degree of protection | IP20 (IP54 optional) | IP66 / IP67 / IP69K |
| Mechanical durability | 50,000 cycles | 10,000,000 cycles |
| Contact form | SPDT (multiple ratings) | 1 NO, slow-break |
| Typical load | Motor / heater / appliance main circuit | Contactor coil / PLC input |
| Certifications | TÜV, CE, UL | UL Listed, CSA, DNV, BV, LROS |
Why the life ratings look so different
The mechanical-durability gap (50,000 vs 10,000,000 cycles) is not a quality gap — it reflects the load. A power button switches 30 A DC or 16 A AC on every stroke, so contact wear is the design driver; a control button switches a few amps at most, so the mechanism can be optimized for millions of cycles. Specify the class that matches your circuit and both products deliver their rated life.
Application guide
| Application | Circuit type | Recommended class |
|---|---|---|
| Handheld power tool main switch | Motor load, 10–30 A | Power (DKLD AN series) |
| Vacuum cleaner / garden tool switch | Motor load, 10–16 A | Power (DKLD AN series) |
| Machine panel start/stop | Contactor / PLC, ≤6 A | Control (XB4-class) |
| Appliance main switch with lock | Load circuit | Power with lock (DKLD AN04-LOCK) |
| Waterproof industrial panel | Control or signal | Control, IP66+ or DKLD AN18 waterproof-cap |
FAQ
Can DKLD AN series replace a Schneider XB4 push button?
Not as a drop-in: they serve different circuit classes. AN series is a power switch (up to 30 A DC, EN 61058) for tool/appliance main circuits; XB4 is a control button (≤6 A AC-15, IEC 60947-5-1) for panel signalling. Select by the load your button must switch.
How do I tell power buttons from control buttons?
Check what the button switches: a motor, heater or appliance (power class, 10–30 A) or a contactor coil / PLC input (control class, ≤6 A). The certification standard is a strong signal — EN 61058 for appliance switches, IEC 60947-5-1 for industrial control.
Does DKLD make a UL-certified push button?
Yes — the AN series is certified to both EN 61058 (TÜV/CE) and UL 61058, covering US and EU export in one model.
Is there a waterproof DKLD button?
The AN01-2 is available in an IP54 version, and the AN18 series offers a waterproof-cap variant for damp industrial environments.
Why is XB4's mechanical life 200x higher?
Because it switches a fraction of the current (≤6 A vs up to 30 A). Power switches trade cycle count for contact capacity — 50,000 cycles at 30 A DC is the industry norm for this class.
