What are the key features of 6425.0101?
- 100 mA / 28 V DC contact rating provides robust switching capacity for indicator and control circuits in industrial panels
- Integrated LED illumination hole allows direct backlight installation without panel drilling or additional hardware
- SPST momentary 0-(1) action delivers clean make-and-break switching for command and interlock functions
- PCB-mount termination enables direct board soldering, simplifying assembly and ensuring low contact resistance
- Compact key-switch form factor suits front-panel, dashboard, and operator-interface installations in space-constrained enclosures
What is 6425.0101 used for?
The MARQUARDT 6425.0101 is designed for operator control panels in industrial machinery, medical equipment, and vehicle dashboards where a key-actuated momentary SPST switch with LED indication is required. Its 28 V DC rating and PCB-mount design suit 12 V and 24 V system control buses common in automotive and industrial applications. The integrated LED hole enables illuminated key-switch assemblies that signal active states directly on the panel face.

Frequently Asked Questions
What electrical ratings define the safe operating envelope of the MARQUARDT 6425.0101 key switch?
The MARQUARDT 6425.0101 is rated for 100 mA maximum switched current at up to 28 V DC, covering the full range of 12 V and 24 V control circuit switching in industrial panels and vehicle dashboards. Operating within these limits ensures reliable contact life and prevents arcing at the SPST contacts during normal make-and-break switching of relay coils, signal lines, or LED drive circuits.
How does the LED illumination hole in the MARQUARDT 6425.0101 simplify panel indicator integration?
The built-in LED hole in the 6425.0101 allows a standard 3 mm or 5 mm LED to be pressed into the key cap without additional panel cutouts or indicator holders, saving assembly time and reducing panel hardware cost. This lets designers route a 12 V or 24 V indicator signal directly behind the switch, creating an illuminated momentary key that confirms operator input or active machine status in a single compact unit.
Which control panel and vehicle dashboard applications are best served by the MARQUARDT 6425.0101?
The MARQUARDT 6425.0101 is well suited for operator interface panels in industrial machinery (start/stop, jog, interlock), automotive dashboard controls (28 V accessory enable), and medical equipment operator stations where a key-actuated, tamper-resistant momentary switch is required. Its PCB-mount design with 28 V DC rating aligns with 12 V automotive and 24 V industrial bus standards used across these segments.
How does the PCB-mount termination of the MARQUARDT 6425.0101 affect assembly reliability compared to panel-wired alternatives?
The PCB-mount termination of the 6425.0101 eliminates solder-less crimp or screw connections by soldering the switch pins directly to the PCB, achieving contact resistance below typical wired alternatives and improving vibration resistance in mobile and industrial environments. At 100 mA and 28 V DC, the soldered joint also handles thermal cycling better than a crimped wire termination over thousands of switching cycles.
