Essex Engineering has manufactured coin slide mechanisms for over 50 years. The coin slide has proved itself highly reliable and easily repairable, resulting in over 1 million finding their way onto coin slide operated machines throughout the world. Coin slides will work in the Namibian desert just as well as in a rain forest or an Eskimo’s igloo. Coin slides are also, of course, totally free from any wiring problems allowing the device to operate anywhere – and use only the energy supplied (quite freely) by the customer!
Keep it simple and design it to take the Essex coin slide.
