JR Products Mini Rockers vs 40A Heavy-Duty Reversing Switches
JR Products makes compact mini rockers and physically larger heavy-duty reversing controls. The mini group includes two-terminal on/off and six-terminal on/on designs, while the high-current switches are spring-return DPDT on/off/on models. Compare the cutout and 12V circuit before fitting one.
Mini and heavy-duty switch comparison
Compare the original device's switching action and manufacturer number. On mobile, scroll the table sideways for all specifications.
| MPN | Switch action | Terminals | DC rating | Cutout (in) |
|---|---|---|---|---|
| 12785 | Mini maintained SPST on/off | 2 | 10 A @ 14 VDC | 0.745 × 0.500 |
| 12795 | Mini maintained SPST on/off | 2 | 10 A @ 14 VDC | 0.745 × 0.500 |
| 12805 | Mini maintained DPDT on/on | 6 | 10 A @ 14 VDC | 0.745 × 0.500 |
| 12815 | Mini momentary SPST on/off | 2 | 5 A @ 14 VDC | 0.745 × 0.500 |
| 12825 | Heavy-duty momentary DPDT on/off/on | 6 | 40 A @ 12 VDC | 1.25 × 0.84 |
| 12835 | Heavy-duty momentary DPDT on/off/on | 6 | 40 A @ 12 VDC | 1.25 × 0.84 |
Mini does not mean low-current substitute. 12785, 12795, 12805 and 12815 fit a 0.745 × 0.500-inch opening. The 40A 12825 and 12835 are momentary DPDT reversing switches needing a 1.25 × 0.84-inch opening and suitable motor wiring.
Selection and wiring checks
- Measure the existing panel cutout, not just the visible rocker face.
- Match the pole/throw configuration and terminal quantity: SPST two-terminal is not the same as six-terminal DPDT.
- Distinguish maintained 12785/12795 from momentary 12815 and the larger momentary 12825/12835.
- Match the real DC rating. The 40A at 12V rating is specific to 12825 and 12835.
- Check wire gauge, fuse/breaker, connector and the motor circuit diagram before installation.
