About this model

This is a complete redesigned and improved version of a modular rotary switch using standard micro switches. It consists of one or more switching layers with up to 4 micro switches in each layer and one stepping layer which defines the switching positions and the number of steps. All parts are designed to be printed without support material and without bridges. External parts needed: - micro switches standard size 20mm x 10mm x 6.4mm without extra lever (can be removed easily if present). The number of required micro switches depend on the number of switching layers and the number of switches per layer (up to 4 per layer). The shown example uses one switching layer with 4 micro switches. I'm using type "KW11-3Z 5A 250V". - heat-set insert nuts M2.5(OD3.5mm), length 3mm: two per microswitch…
