Generic aftermarket switches may vary in trip temperature and terminal geometry, which can cause nuisance lockouts or improper safety response. For a life-safety component like a rollout switch, we strongly recommend genuine OEM.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5)\u003c\/strong\u003e — Two spade terminals and one mounting screw.
