Gold plated contacts and silver contacts solve different micro switch problems. Gold plating protects low-energy signal circuits from oxide and film buildup, while silver alloys carry higher currents and tolerate arcing. Match the contact system to the real circuit before locking...

Long Life Micro Switch selection starts with the installed duty, not a broad catalog label. Define the mechanism, circuit, environment, mounting, and validation target before approving a sample. A component can look similar while carrying different terminal, travel, contact, or t...

Micro switches and reed switches solve different sensing problems: one changes state from controlled mechanical movement, while the other changes state from a correctly positioned magnetic field. Select from the installed mechanism, contact/load requirements, mounting tolerance, ...

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...

A micro switch with cord is a snap-action switch supplied with factory-attached leads so OEM teams can route wiring without soldering every terminal in the field. Specify length, gauge, exit direction, contact rating, and strain relief before approving the harness. Corded conveni...

A long arm micro switch uses an extended lever or arm so a remote cam, door, or linkage can actuate a snap-action contact. OEM teams should define required reach, tip operating force, overtravel limit, mounting clearance, and circuit load before approving a sample. An “extra long...

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, ...

A micro switch for elevator-door equipment can report a defined mechanical state to the door or lift controller. It is not automatically a complete door lock and cannot replace the applicable elevator safety design. Select it from the mechanism travel, safe contact logic, mountin...

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...

An automotive micro switch is a compact snap-action component that reports a defined mechanical state inside a vehicle-adjacent module. The right choice comes from the module drawing and validation plan: actuator travel, contact load, mounting tolerance, vibration, sealing, wirin...

A water heater micro switch is typically a snap-action safety interlock that confirms a mechanical or logical safety condition before heating is enabled—not a replacement for a bimetal thermostat or thermal cutoff. OEM teams should define the safety chain, contact rating, actuato...
