 PS20A Pneumatic Switch 

The PS20-A pneumatic switch offers a reliable, low cost alternative to the standard electric SensingEdge. The PS20 operates as an effective SensingEdge when attached to a hose that is inserted into the existing weather stripping on most doors.

PS20 kits come in many sizes and can be installed on a door up to 18 feet wide.
