When is a plain lever or long lever right?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Plain levers absorb approach-angle variation and reduce the force a mechanism must deliver. Longer arms trade operating force against a wider tolerance on the operating position, so the drawing must show where in the stroke the circuit changes state.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">For extended-reach cases with cams or linkages, the <a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/lemaele.com\/es\/blog\/long-arm-micro-switch-selection-guide\/\">long arm actuator selection guide<\/a> covers arm length, force, and repeatability in detail.<\/p>\n<h2 id=\"part-3-when-do-roller-actuators-earn-their-cost\" style=\"margin:42px 0 14px;scroll-margin-top:96px\">Part 3. When do roller actuators earn their cost?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Rollers replace sliding friction with rolling contact, which protects both the cam surface and the actuator on frequent cycles. They earn their cost on sliding profiles, conveyor cams, and any surface that would abrade a plain lever tip.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Roller-specific geometry questions, including approach angle and cam design, are covered in the <a style=\"color:#f27c00;text-decoration:underline\" href=\"https:\/\/lemaele.com\/es\/blog\/roller-micro-switch-selection-guide\/\">roller actuator selection guide<\/a>.<\/p>\n<h2 id=\"part-4-how-do-plunger-and-button-styles-behave\" style=\"margin:42px 0 14px;scroll-margin-top:96px\">Part 4.
