Abstract
A pinch detection switch includes a pressure sensing structure including at least one linear pressure sensing member with multiple conductor wires spaced apart from each other in an inner side of a tubular elastic body, and a tubular cover member to be attached to an end on a forward side in a moving direction of a movable body, and which is formed with a hollow portion which receives the pressure sensing structure. The pressure sensing structure includes a coating member which covers the at least one linear pressure sensing member, and which faces an inner surface of the hollow portion at both its ends in a width direction orthogonal to the moving direction of the movable body and an extending direction of the cover member. A position in the width direction of the at least one linear pressure sensing member in the hollow portion is defined by the coating member.
