A17 ‘Snap-In’ Ignition Lock Barrels & Switchies


These are well-known ‘Lucas’ keyoperated 24 volt rotary switches, suitable for commercial, agricultural and industrial uses. The model shown suits diesel engines, with the most commonly used terminal configuration, many other versions available.

WBH ignition barrels have a spring-loaded plunger, allowing ‘snap-in’ fitting. They can be supplied to special key number, allowing ignition to be matched to a full vehicle lock-set. ‘Shuttered’ head for weather-protection when required.
