OIL PRESSURE SWITCH, HOW BRITTLE ARE THEY?

[rmuntan]

I am just checking to see if this switch is defective or it was installation error,I did just change this and did not see any oil under the car until last night , just been 3 days, not as much as before but still a drop is a drop and leaks always get worse.
When I installed it I dropped it.....not once but twice, oooppsss, not a great distance to drop but still it did drop, I am seeing oil leak not at the engine and switch but at the connector itself. That is why I am asking if anyone has had any experience with these being brittle or maybe it was faulty to start with.
