Acorn 180 Curved Stairlift genuine OEM replacement parts in good used condition. 100% functional, tested, and sourced from operational Acorn 180 system. Components also fit Acorn 130 Superglide models that share the same seat assembly.

The seat interface board / PCB provides the clearing house for chair -> carriage / motor signals. Specifically, each arm contains a toggle switch that controls motion and direction of the lift. In addition, each arm contains a microswitch to indicate when the respective armrest is in "down" position (required for lift movement / operation). Both of these signals are passed to seat interface board / PCB from each arm. The board also has a connector for seatbelt reserved for future implementation, presumably to determine whether or not seatbelt is in use.

This interface board / PCB is mounted to rear side of the backrest with two included mounting screws. A protective cover and mounting screws are also included. Wiring harnesses are not provided (ie conneting armrest and toggle switch to board; conecting board to carriage / motor assembly). The components are available individually in accord with specific need(s). Some components may be available in our store:
