Johnson Electric V3S Discontinued: SI-V3S as 1:1 Compatible Replacement
The microswitch Johnson Electric V3S is officially discontinued and no longer available from April 2026. As a long-standing partner, we offer the SI-V3S as a fully compatible alternative from switch-it – identical in all relevant parameters, usable without any design changes.
Technical Specification
Drop-in replacement without re-qualification. All critical tolerances and switching characteristics correspond to the V3S.
| PARAMETER | VALUE | NOTE |
|---|---|---|
| Dimensional accuracy | SP 14.5 ±0.5mm | Switching point identical |
| TTP | max. 13.4mm | Total Travel Position |
| Operating force | 3.9N | Operating Force |
| Mechanical life | 10⁶ cycles min. | Life identical |
| Temperature range | -40 to +85°C | Automotive standard |
| Protection | IP67 | dust-tight |
Risk-Free Changeover
✓ Plug & Play: Same form factor, same drilling patterns, same switching points – SP 14.5mm
✓ Automotive proven: BMW N600 13.0 climate test passed (-40 to +85°C)
✓ IP67 sealed – for demanding automotive and industrial environments
✓ Available from stock – Variants: Plain Lever, Roller Levers, wire / lever customized
YOUR ADVANTAGE
0 Design Changes | 10⁶ Cycles Minimum
We take over your V3S BOM 1:1 and deliver with identical coding.
Discontinuation Notice
Johnson Electric has discontinued microswitch type V3S via PCN. Last delivery date April 2026. For new developments and ongoing series, switch-it recommends changing to SI-V3S. Dimensional accuracy SP 14.5 ±0.5mm and TTP max. 13.4mm remains identical, as well as switching performance (operating force 3.9N), mechanical life 10⁶ cycles incl. climate test according to BMW N600 13.0 and protection class IP67.
