I would like to convert the speed dial on a record player I am modding to a two button system. The dial has three positions: OFF, A, B (corresponding to 33 and 45 rpm). The control I would like is two buttons. When A is pushed, the player spins at 33 rpm. If A is pressed again, it turns OFF. If B is pressed it spins at 45 rpm, irrespective of whether A is ON or not.
My first thought is that I want two latching switches with a mechanism that breaks the other switch before making itself. Is there a name for this type of switch or a simple way of achieving this?
