Description
When you’re trying to get your old Case tractor fired up on a cold morning and the heater won’t kick in, there’s a good chance this little switch is the culprit. If you’ve been starting your DED3, DGD4, or DLD2 and waiting forever for the cab to warm up, or if the heater just won’t turn on at all, this 4-pin ignition switch controls the power flow to your heating system and gets things working like they should.
What You’re Getting
- Heavy-duty 4-pin switch rated for 12A at 12V and handles the electrical load without burning out
- Galvanized steel housing and gear lever that won’t rust or corrode in harsh conditions
- Aluminum-stained octagonal mounting nut for secure installation that stays put
- 2-minute duty cycle design built specifically for heater ignition applications
Built for Real Farm Work
This switch fits the Case IHC BD Series tractors – the DED3, DGD4, and DLD2 models that are still earning their keep on farms across the country. These utility tractors handle everything from feeding cattle to moving snow, and when the weather turns cold, a working heater isn’t just comfort – it’s safety. You need clear windows and warm hands to operate controls properly.
Made to Last
The galvanized steel construction handles the vibration and temperature swings that come with tractor work. The electrical contacts are sized to handle the heater’s power draw without arcing or premature wear, and the octagonal mounting nut provides a solid connection that won’t work loose over time.
Good to Know
This is a direct replacement for the original switch, so your existing wiring should connect right up. Before installation, disconnect the battery and take a photo of the wire connections so you can get everything hooked up correctly. If your heater still doesn’t work after replacing the switch, check the heater motor and wiring – sometimes these old systems need a complete going-over to get back to working right.
