Thwaites Dumper Ignition Switches

Thwaites dumpers are the largest selling dumper in the UK and PES is the largest stockist of genuine Thwaites parts. From our stock of over £750k of dumper parts, PES are able to supply genuine Thwaites ignition switches from stock for next day delivery.

For those of a certain age who can remember electric start Lister Petter engines in Thwaites dumpers with just a Lucas ignition switch, things have moved on a bit since then and to comply with legislation Thwaites, as all manufacturers have, are now producing dumpers with quite complicated electrics on. The Thwaites ignition switch has moved on since the Lucas switch as well and instead of just operating a starter motor the Thwaites ignition switch is the starting point for safety systems, ECU controls, lighting equipment, engine pre-heat and a myriad of other complex electrical circuits. This is for Thwaites dumpers without a cab, the cabbed Thwaites dumpers also have air-conditioning, heaters, USB connections amongst other things which brings another load of switches, control panels, relays, sender units and warning buzzers into the equation. When your Thwaites ignition switch fails it’s not the case of bodging an old Lucas switch on, a lot of the more modern Thwaites ignition switches connect directly on to the Thwaites loom via a plug. The days of crimped Lucas connectors are over and therefore to avoid problems it is recommended that you only fit a genuine Thwaites ignition switch to your Thwaites dumper. Why compromise by trying to save a few pounds on a Ebay switch or a cheap Chinese copy from one of the aftermarket ‘on-line dumper specialist’ for your Thwaites dumper. After all you don’t want your cheap, Chinese ignition switch shorting out and burning the starter motor and loom out on your £26k worth of Thwaites dumper. Keep it genuine………….you know it makes sense.
