How to Wire a Micro Switch for an OEM Assembly

Wire a micro switch only after identifying the approved terminals, intended contact state, circuit load, wire route, and isolation method. COM, NO, and NC labels describe a contact relationship; they do not by themselves prove that a component is suitable for every voltage, curre...

Selecting a Micro Switch for Refrigerator Door Sensing

A micro switch for refrigerator equipment normally reports a door or mechanism state to lighting, fan, alarm, or controller logic. It is not automatically a thermostat or defrost controller. OEM teams should define contact logic, actuator travel, mounting, condensation exposure, ...

Selecting Micro Switches for Vending Machine Functions

A micro switch for vending machine equipment is usually a discrete position or interlock input: it can report a service-door state, confirm a vend-mechanism position, or provide a mechanical signal to the controller. It does not independently authorize a payment or replace the ma...

IP67 Micro Switch With Cable: OEM Harness Selection Guide

An IP67 micro switch with cable keeps the ingress seal at the factory-potted lead joint, so OEM harnesses must specify wire type, exit direction, contact rating, and actuator type before approval. This guide helps appliance, industrial, and outdoor-equipment teams select pre-wire...
