Key Features
- Double-pole double-throw (DPDT) switching in a low-profile 21000N series body for compact panel layouts
- Straight PC board terminals enable direct soldering to PCB without flying leads, reducing assembly time
- Threaded metal bushing provides secure panel-mount fastening with standard 12 mm mounting hole diameter
- Rated at 4 A / 250 V AC for reliable switching in industrial control and consumer electronics power circuits
- Low-profile actuator design minimizes protrusion height above the panel for space-constrained equipment enclosures
Applications
Apem 21146AN is widely used in industrial control panels, test instruments, and laboratory equipment where a compact low-profile DPDT toggle switch must control dual independent circuits from a single actuator. Its straight PCB terminal design suits dense electronic assemblies in medical devices and communications equipment that require reliable switching at up to 250 V AC. The threaded bushing mounting also makes it a practical choice for front-panel controls in rack-mount enclosures and ruggedized field instruments.

Frequently Asked Questions
What electrical ratings does the Apem 21146AN toggle switch carry for industrial power circuit applications?
The Apem 21146AN is rated at 4 A at 250 V AC, making it suitable for switching mains-voltage auxiliary circuits, indicator lamp supplies, and low-power motor controls in industrial control panels and laboratory instruments that require DPDT switching at standard line voltages.
What pole-throw configuration does the 21146AN provide, and how does that benefit dual-circuit switching designs?
The 21146AN is a double-pole (DP) toggle switch, meaning a single actuator simultaneously controls 2 independent circuits; this is valuable in equipment requiring simultaneous enable of both live and neutral lines, or in switching between two signal sources, without needing to gang two separate single-pole switches.
How is the Apem 21146AN mounted to a panel, and what panel cutout does it require?
The 21146AN uses a threaded metal bushing with a standard 12 mm mounting hole diameter, secured with a hex nut; the low-profile actuator extends approximately 14 mm above the panel surface, and the straight PC terminals allow the switch to be soldered directly to a PCB positioned behind the panel for clean internal wiring.
When would a designer select the 21146AN over a PCB-mount SMT switch for the same DPDT function?
The 21146AN is preferred when the switch must be accessible on a front panel or enclosure face for operator use, since its threaded bushing provides a secure 12 mm panel-mount interface at 4 A / 250 V AC; SMT switches rated below 1 A and buried on the PCB cannot provide the same operator-accessible, high-current-rated actuation that the 21146AN delivers.
