Cole Hersee’s recessed toggle switch is meant especially for trucking applications. It’s a standard toggle switch centered at the bottom of a plated steel bowl measuring .892 in. deep. This new design mounts in the cab or body, and prevents accidental actuation by the driver, or by personnel loading or unloading cargo. The steel casing fits into a 2-in.-diameter hole and has an outer rim diameter of 3 3/16 in. (81 mm). The rim also has three holes for mounting.
