Plastic Thin Plunger 1CO MK1 Series Micro Switch
The MK1PUP1 replaces the lever actuators of the rest of the MK1 range with a thin plunger, giving a precise, direct-acting trip point for straight-line linear detection rather than an angled lever sweep. It's the choice when your actuating part moves directly onto the switch rather than approaching from an angle.
A versatile and rugged micro switch from EMAS suitable for many different applications.
10A rated for resistive loads or 6A for inductive. By choosing EMAS you can be assured of safety and quality, microswitches are UKCA and CE marked.
Changeover contact allows for normally closed or normally open wiring. Fast on crimps or soldered connection.

Frequently Asked Questions
When should I choose a plunger over the lever variants?
Choose the plunger when your actuating part moves in a straight line directly onto the switch, rather than approaching at an angle — the lever variants (MK1KIM/MIM series) suit swinging or angled actuation instead.
Why is it rated both 6A and 10A?
6A is the standard AC15 inductive load rating; 10A applies to purely resistive loads.
Can I wire this as normally open or normally closed?
Yes — the changeover (C.O.) contact supports either wiring configuration from the same part.
Is this suitable for washdown areas?
It's IP20 rated, suited to standard indoor equipment rather than washdown or outdoor environments.
Industry Applications
- Linear position detection — precise straight-line actuation where a lever isn't suitable
- Machine guarding & interlocks — direct-acting detection in compact spaces
- Panel builders & OEMs — general-purpose end-of-travel switching
