Non-electrical step switch to generate reversible, linear or rotary motion

摘要

A rotary switch has a block (1) surrounding a central cylindrical cavity in which a switch rotor (5) is installed with a series of teeth (51) around its circumference. The block has three or more passages linking the cavity with the outside, and holding pneumatic switches (2, 8). The intervals at which the pneumatic switches are installed does not coincide with the pitch of the teeth (51).
