Micro Switch Pretravel, Overtravel and Differential Travel Explained
Micro switch pretravel overtravel differential should be selected by matching the electrical function, mechanical interface, environment, and verification plan—not by copying a generic diagram or choosing from appearance alone. Pretravel is actuator movement before contact transfer; overtravel is the permitted movement after transfer; differential travel is the distance between operate and release points. These terms describe different parts of the motion envelope and should never be substituted for one another on a drawing or inspection report. This guide gives engineers and OEM buyers a practical way to define the requirement, compare samples, and avoid a part that works on the bench but fails after installation. Product-focused application view based on the corresponding LEMA website product image. What the term means in this application Pretravel is actuator movement before contact transfer; overtravel is the permitted movement after transfer; differential travel is the distance between operate and release points. These terms describe different parts of the motion envelope and should never be substituted for one another on a drawing or inspection report. The first job is to separate the switch's name from its required behavior. Product names are often shortened for search or purchasing, while an engineering drawing defines the contact state, terminal numbering, operating point, allowable travel, mounting reference, and ratings. If those details are missing, two parts with similar names may behave differently. Write the control requirement as a short sequence: the condition before actuation, the physical action that causes actuation, the electrical state after actuation, and the condition that resets it. This sequence prevents confusion between mechanical action and contact logic. It also gives the controls engineer, mechanical designer, buyer, and supplier one shared description to review. Do not...
↗IEC C13 vs C14: Connector Differences and Compatibility
C13 vs c14 should be selected by matching the electrical function, mechanical interface, environment, and verification plan—not by copying a generic diagram or choosing from appearance alone. C13 is a cord connector and C14 is the matching appliance inlet in the common IEC 60320 family. They are complementary parts, not interchangeable names. Compatibility also depends on current, voltage, temperature class, cord construction, approvals, and the equipment's inlet orientation. This guide gives engineers and OEM buyers a practical way to define the requirement, compare samples, and avoid a part that works on the bench but fails after installation.

↗Normally Open vs Normally Closed Push Button Switch
Normally open vs normally closed push button should be selected by matching the electrical function, mechanical interface, environment, and verification plan—not by copying a generic diagram or choosing from appearance alone. Normally open and normally closed describe the electrical state when the button is not actuated. They do not describe momentary versus maintained action. The safest choice depends on the control objective, fault response, monitoring logic, and the requirements of the finished machine.
