Foot Pedals

Model FP10

FEATURES

▶ 0 – 5k potentiometer output easily interfaces with motor controller 

throttle inputs and avoids the necessity of a dedicated power supply.

▶ Dual return springs to ensure safe operation.

▶ Return spring failure detection allows the vehicle designer to 

implement a limp-home mode to ensure that the vehicle can return 

to a safe location thereby eliminating stranding the vehicle (see 

wiring diagram below).

▶ The foot pedal includes two microswitches to indicate idle validation 

and full throttle further ensuring safe vehicle operation.

▶ Flexible design allows the foot pedal to mounted on the floor or 

suspended on the firewall, to locate the pedal on the right or left side 

of the unit and adjust the pedal to the desired angle.

▶ The foot pedal is protected to IP67 and is rated for operation from 

–40°C to +85°C to ensure reliable and safe use in harsh environments.

▶ Glass filled nylon housing and pedal ensure reliable operation in 

demanding applications.

▶ The FP-10 is rated for 1 million cycle operation over its full 

specification thereby ensuring that it lasts for the life of the vehicle 

while minimizing operating costs.

Curtis Model FP-10 foot pedals are designed to be a reliable, safe and easy-to-install 

throttle for industrial battery powered vehicles. Model FP-10 offers dual return 

springs with fault detection on those springs to allow throttle fault detection as well 

as the ability to implement a “limp-home” mode.
