PROBLEM TO BE SOLVED: To provide a pressure switch capable of achieving complete electrical connection between a diaphragm and a fixed contact even when foreign matter invades between a summit of a bent section of the reversed diaphragm and the fixed contact, and capable of setting a contact position to the fixed contact of the summit of the bent section of the diaphragm at a stable contact position without increasing a contact resistance.SOLUTION: When a diaphragm 20B in a pressure switch is reversed, a cross-shaped abutting surface 13bt at a fixed contact 13 is abutted at four positions against an annular contact section 20br in the diaphragm 20B.SELECTED DRAWING: Figure 5 |
