The invention relates to biological experiment equipment and particularly relates to a pedal type induction switch of a biological laboratory door. The pedal type induction switch comprises a shell body, inductors and a baffle, wherein the inductors are located on the two sides of the shell body and the baffle is arranged at an opening of the shell body; the corner of an inner connector of the shell body is circular-arc-shaped; the bottom of the outer part of the shell body is in a bent shape. A handle can be prevented from contact, and pollution is prevented from diffusion. An external switch is used for controlling the door and the switch has a wide installation range.
