MK1KIM3, EMAS, microswitch, MK1, lever, 1 CO

MK1KIM3 is a microswitch made by EMAS. This page describes a specific order variant, not just a general product line.

In industrial automation the exact order code is essential: similar-looking variants may differ in contacts, operating element, degree of protection, electrical parameters or compatibility. Catalogue parameters, recommended use and checkpoints before ordering are therefore listed separately below.

Operating principle

A mechanical microswitch changes the contact state when the plunger, lever or roller is pressed. The CO changeover contact allows the normally closed and normally open branches to be used depending on the wiring.

Typical applications

Typical uses are detection of position, control cabinet doors, a mechanical stop, movement of a small lever or as an auxiliary contact in machine mechanisms.

Technical specifications

Mounting and wiring

Set the mechanical cam so that the switch operates reliably but is not permanently overloaded. For lever and roller variants, observe the correct direction of movement.

Before commissioning, check the mechanical operation, electrical function and secure fastening. When replacing an original part, also compare the orientation of the cable, connector or actuator and the available mounting space.

How to choose the right variant

Compare the contact type, actuator, material of the actuating part, degree of protection and electrical load.

Compatibility and replacement

When replacing, compare the original order code, contact function, mechanical design, degree of protection and electrical load. For accessories, the exact compatible series must also be verified. If a parameter is not stated in the available source data, it is not assumed in this description.

Operation, inspection and service

Check the mechanical wear and cleanliness around the switch. If switching is irregular, check both the cam and the contact condition.

After replacement or a change of mechanical setting, always carry out a functional test in the real working range of the machine. For elements that affect stopping or interlocking of the machine, also test the related control logic.

Source of technical data

Technical data were added from the user-supplied EMAS Product Overview catalogue, edition 57, catalogue page 49, and from the e-shop source export.

The catalogue and source text was used for the parameters of the specific variant. Technical values not documented in the available sources are not added to the description.

FAQ

What kind of product is MK1KIM3?
MK1KIM3 is a microswitch made by EMAS. The exact design and parameters of this variant are listed in the technical table.

How to verify that MK1KIM3 is the correct variant?
Compare the complete order number, product function, mechanical design, electrical parameters and compatibility with the specific assembly.

Why is a similar appearance or name not enough?
For industrial components, a small change in the code can mean a different contact, actuator, voltage, connector or a different function.

What should be checked before ordering?
Order code, contacts, mechanical design, degree of protection, electrical parameters and connection method. For accessories also the compatible series.

How to proceed when replacing the original part?
First copy the complete code of the original part. Then compare the function, dimensions, wiring and mechanical method of operation.

Can the product be used in another application?
Yes, but only if the technical and mechanical conditions match. The same product line by itself does not guarantee interchangeability.

What does a CO contact mean?
CO is a changeover contact with a common terminal that switches between the normally closed and normally open branches.

What kind of cam should be used on the switch?
The cam should actuate the switch in the permitted direction and must not push the actuator beyond its mechanical range.

Is it suitable for frequent switching?
Suitability depends on the electrical load and the mechanical cycle. Do not exceed the values stated for the specific switch.

How to recognise a worn microswitch?
Symptoms may include irregular switching, increased mechanical play or a change in the switching point.
