This is a basic mechanical acceptor. The coin is measured for diameter, width and metal content. If the coin is accepted it passes a microswitch with Common, Normally Open and Normally Closed contacts, which in turn will give a credit to your game. Ideal for home arcade cabinet builds or as a replacement mech for older machines. This mech can be used for a wide variety of applications that require a coin input to operate and it is very reliable compared to the more advanced coin mechs.
Some of our customers have used these for operating snooker table lights, model trains, public toilets and kiddie rides.

The mech will also connect to a Mini-PAC or I-PAC. It is very easy to install - just take the coin signal wire from your appliance and connect to the NO (Normally Open) microswitch terminal on the back of the mech. Connect the ground wire to the CO (Common Ground) terminal on the microswitch and that's it! It is an ideal mech for first time cabinet builders and more experienced arcade cab builders. This is the same mech that many of the arcade machines in the 80's used. Give your home arcade cabinet a real retro feel and turn your machine into a giant money box at the same time!

*Please Note:
The 10p version of this coin mech IS now compatible with the newer nickel-plated steel version of 10p coins that were introduced from early 2013 onwards AND older 10p coins (Pre-2013)

    Excellent mechanisms

    Posted by Jon Ashton on 10th Jan 2021

    Having switched from the cheap, plastic, programmable mechanisms to these, I'll never go back. These are pure mechanical and don't fail. There is no tedious set up, simply hook the 2 micro switch points to your controller/encoder and that's it, no power required. They're very well made, all steel, so I can't see these even failing after heavy use.
    Highly recommend.

    Mechanical coin acceptor

    Posted by Steve Kelley on 23rd Nov 2017

    We required a one pound coin acceptor for a timed heater at our club and originally purchased an electronic version, after three replacements however we changed to your mechanical version. Far superior product, would only consider using these in future projects.

    replacement mechanical coin mech on new £1 coin

    Posted by Robert Hind-Smith on 21st Apr 2017

    The coin mech was purchased to replace a mechanical Coin Controls mech of a similar shape and size. and the new mechs shape ,size and look is obviously designed to mimic the Coin Controls design.
    However the fixing holes of the new coin mech do not align exactly and two have to be drilled out to fit.
    The most frustrating aspect is the new mech has the microswitch terminals stuck out at right angles to the side which does not fit within the standard case surround.
    The original Coin Controls mech has the microswitch fitted underneath the mech with the terminals to the rear which is a far better design. I have been able to make the new mech fit but it requires additional work.

    What a Product!

    Posted by Unknown on 13th Apr 2017

    When people were saying you won't be able to upgrade a 1978 Bell Fruit pub machine. I ordered a 10p mechanism and then after that worked a 20p. Excellent service and easy to fit and wire up.

    it just works.

    Posted by Lee on 17th Sep 2016

    as the headline.. couple of wires and its all go.. very slight adjustment to the coin ring collector on reject but nothing to really write about. Got this for a Defender desktop I made and works perfect.
