Control-switch for vehicle heating and air-conditioning system

摘要

The single control (5) has a slide-action parallel to contact strips (11) to control the blower speed and a twist action to set the temperature. If the air-conditioning is selected while the blower setting is zero, a mechanical cam (7) operates against a fixed support (8) to displace the blower slider control to the first blower setting. The twist control has a radial flap (6) with a contact strip (10) which bridges the parallel contact strips in the blower control setting. A cams (7) rotating with the control is shaped to interact with the fixed point and to move the slider through the reaction force.
