Q: What is a Glow Plug Switch?
A: A Glow Plug Switch is a device used to provide electrical power to a vehicle's glow plug system. The switch is connected to the vehicle's battery to supply power to the glow plugs which then warm the air inside the engine's cylinders.
Q: How does a Glow Plug Switch work?
A: The Glow Plug Switch works by providing electrical current from the battery to the glow plugs, which then heat up the air inside the engine's cylinders. The amount of current supplied depends on the temperature inside the engine, and is regulated by the Glow Plug Controller.
Q: What are the benefits of a Glow Plug Switch?
A: Using a Glow Plug Switch provides improved engine starting performance, better fuel economy, and improved exhaust emissions. It also helps to reduce wear on the glow plugs since they are heated up at the optimum temperature.

Ring RTC Tyre inflator
Bought the tyre inflator because of the unreliable service station tyre inflators.
The buying process online through APD was straightforward. Ordered the tyre inflator late afternoon and received it 2 days later via the Royal mail.
I have a car, campervan and motorbike. I like the wind in cable feature keeps everything neat and tidy. The inflator is easy to use on all three vehicles. Appreciated the chocolate.
Very quick despatch and delivery time
Good updates. Items exactly as described. All fitted and car back on the road.
Personally I found them to be very...
helpful response to emails relating to my purchase was within the hour and they offered the best price on the parts I needed had to wait a couple of days longer than usual due to the parts that I needed was out of stock (but I was made aware of this before ordering) would happily use them again.
Very helpful company.
I ordered a cabin filter on their website which was out of stock. They contacted me by email & offered a replacement which wasn't really what I wanted so they immediately sent a refund. I found another that was suitable, they happily ordered it for me and called me when it arrived in my local store to collect.
Helpful people giving great service
The Wiper blades I ordered were competitively priced and promptly delivered. Unfortunately there was an issue with the fitment and this is where APD showed their commitment to great customer service. They were most helpful in resolving the problem to my complete satisfaction.
