Truma window switch prevents operation/cut out of LPG heaters with open windows if the cowl is installed below the window or up to 30 cm beside it.

This innovative switch has been meticulously designed to enhance safety by automatically shutting off the heater when a nearby window is opened. This is particularly critical when the heater's exhaust, such as those from Truma Combi or VarioHeat units, is mounted close to a window.

Universal for most campervan/motorhome/caravan hinged windows. 

Suitable for all Combis, Trumatic C, Trumatic E,

 Comes with:
