Mechanical Thermal Switch Combo - Part No: 0400

This product combines part numbers 0401 & 0409 into a convenient and economical value pack and can be used with our Thermatic Fans & EWP's. The mechanical switch senses the coolant temperature after it passes through the engine block prior to entering the radiator & is fitted directly into the radiator hose via the adaptor. It is adjustable from 40 to 100 degC. The kit comes with everything you need for a watertight and effective installation. We even supply rubber sleeves to enable fitment to radiator hose sizes from 32 to 40 mm diameter.

*Note: if using this switch for use with our EWP's, it will not vary the speed of the pump in response to engine temperature but rather turn the pump on and off at your set temperature. For EWP control, we would recommend part number 8020 which can manage both the EWP and your Thermatic Fans. 


Mechanical Thermal Switch (12V & 24V) (Part 0401)
The Mechanical Thermal Switch is adjustable from 40° to 100°C
(104° to 212°F). The thermal switch is mounted near the radiator and the stainless steel probe fitted inside the radiator hose. The thermal switch is then connected to the ignition circuit for operation. The thermal switch and relay kit enables a fan to operate both thermally and also when the air conditioning is running.


Temperature Sensor Adaptor Kit (Part 0409)
No need to squeeze the probe of the Mechanical Thermal Switch between the radiator inlet and radiator hose. This simple, economical Adaptor Kit allows easy fitting directly into the radiator hose. Just fit the probe into the compression fitting, remove about 17mm (2/3”) of radiator hose, fit the adaptor between each hose and secure the hose clamps.
The kit comes complete, as shown, for a watertight and effective probe installation. Extra rubber sleeves are supplied to enable fitment to radiator hose sizes from 32mm to 40mm (1¼” to 1½”) diameter. Suits all temperature sensors with a ¼” or 6mm outside diameter and temperature gauge senders with ¼” BSPT thread.
