The memory seat switch or switches enable the driver and passengers to alter the configuration of their vehicle seating to achieve the ideal position for their comfort and safety. Using either a series of buttons or dials on the side of the seat or a single, stand-alone unit, most car seats can be raised or lowered, moved closer or further from the steering wheel and pedals, and the backrest angle changed. The memory seat switch has the ability to store a number of pre-set positions to suit the differing size-range of all drivers and passengers who use the vehicle without the need for manual adjustment for each journey or driver.

Most memory switches allow the driver and passengers to alter the head-rest height, upper seat-back angle, main seat-back angle, seat height, seat length, seat depth, seat angle and lumbar support horizontal and vertical. Some memory seat switches can activate a massage effect in the seat which may alleviate stiffness or back pain on long journeys.

If the memory seat switch fails to operate this may be due to a blown fuse, poor terminal connections or faulty wiring.
