The Access switch comes with a clear screw on cover that screws onto the switch preventing the cover from coming loose or falling off. The screw on cap becomes an integral part of the switch allowing symbols or objects up to 2mm thick to be placed securely under the switch cap without fear of them popping out. Available in small (26mm diameter by 11mm high) and medium (65mm diameter x 23mm high). Both switches have a 1.4m long cable fitted with a standard 3.5mm jack plug. Available in Blue (B), Red (F), Green (G) and Yellow (I). Please add colour option after product code when ordering.
