Thanks Gerald, I will pull mine and take it in with me to compare. As always thanks for the expert advice.
I spent a good portion of the day in my front wheel wells changing out my front hydraulic jack up sensor/switches. One had failed and would tell me the jacks were up when they are not. Funny they used a normally on switch that goes to off when depressed by the hydraulic ram foot....strange. If they were normally open you would get never get a false all up indicator when one failed and you would know something is wrong.
Pretty tight sitting in that wheel well behind the tire....if I get a wrench in my hand and start getting dirty, I usually have a passing thought when I wrap my knuckles, as to how you might have avoided that fate....
