Pushbutton Switches Short Stroke Key Switch
Research Notes
1. What this is
PVA1 EE H3 1.2N V2 is a C&K ELUM/PVA illuminated-pushbutton actuator configuration (this code fragment describes an ELUM actuator: OA=momentary / EE=latching, H#=cap height, #N=force, colour codes) rather than a complete orderable part number.
2. Part-number decode
- Product line: C&K ELUM/PVA (actuator config)
- Type: illuminated pushbutton
3. Compatibility & ordering
C&K makes high-reliability electronic switches for PCB and panel mounting. Match by type (tactile / pushbutton / toggle / rotary), actuation (momentary vs latching), mounting (SMT / thru-hole / panel), and the electrical rating, then use the C&K datasheet to confirm the exact actuator height, force, and termination encoded in the part number.
4. Data-quality note
The exact C&K product line/configuration could not be confidently decoded from this part number (it may be a partial/free-text code fragment). Kept and documented; flagged needs-verification rather than guessed.

Installation Quick Reference
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Troubleshooting
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
