MIG Trigger Switch

[DF Machine Specialties]

Does anyone recognize this trigger switch and know the model number or the model name and number of the MIG torch that used this switch? The switch looks very similar to the Bernard Model F Gun Switch but this switch mounts by sliding it into a slot and screwing it down in the front not on the sides. If anyone has any information about this switch it would be appreciated. I am new to the forum and I tried to post photos of the switch, if they do not post please send me a PM and I can send the photos or email them to anyone ineterested in helping.

Thanks,

Steve
