The Medium Handbrake Kit by Hollin Applications allows the user to either apply or remove a vehicle's handbrake with a force of up to 1300N (130kg) by the push of a button, with built in safety features to ensure no accidental applications or removals of the handbrake occur.
This circuit designed by Hollin Applications uses an input signal to switch the direction of a 100mm MD Linear Actuator.
This actuator has internal end-of-stroke limit switches and has a max load of 2000N (200kg).
The double pole switch changes relays in a H-Bridge configuration which changes the direction of current flow and shorts the D.C. Motor when switched off. This ensures a minimal amount of overrun on the Actuator. This circuit automatically converts the low power input signal to the high current motor drive.
​
The circuit is pre-set to 800N (80kg) and is adjusted by the potentiometer up to a maximum of 1300N (13okg). The kit comes with a simple ON-ON Toggle Switch as standard but other options are available.
