Otter switch
MG: MGB V8 (1973-76)
Jaguar: E-Type Series 1 and 2 (1961-70)
fan motor. Comprehensive kit with a modern solid state switch, brass adapter plate, cork gasket and earth terminal.
The original fan controller switch used by Jaguar, and a host of other manufacturers in the 1960′s and 70′s, was known as an Otter Switch. In its day this unit functioned adequately but technology has moved on and more reliable, solid state alternatives now exist. However, fitting a modern switch to a car originally equipped with an Otter Switch is not always straight forward because of the way the Otter Switch mounts into the cooling system.
In response to the need for more reliable fan control, we have developed this simple kit which allows the original Otter Switch to be replaced with a modern switch. The new switch can be installed without the need to cut water pipes or modify the cooling system in any way.
• switch turns on at 85 °C and turns off at 78 °C
• suitable for negative and positive earth vehicles
• must be used with a relay. If your current fan installation does not include one we will be happy to supply a suitable unit.
