Lock Inhibitor Relay Switch
Inhibits the cab door from locking while the ignition is on. The inhibitor is not required, but is recommended when using Thunderbolt Locks in cab doors. If you are installing Thunderbolts in each cab door two Inhibitor Relay Switches should also be ordered.
Relay Switch Module for Cab Doors
When installing Thunderbolt Locks on the cab doors we highly recommend integrating our Lock Inhibitor Relay Switch to the front door Thunderbolt locks. These inhibit the Thunderbolts from locking while you are driving. This is a safety precaution in case emergency personnel need to access the front doors. When you leave the vehicle all the locks will lock. One Inhibitor Relay Switch is needed in each cab door.
