<P>PROBLEM TO BE SOLVED: To provide a pressure switch which enables substrates and electronic components to be arranged at a center part where the largest space is secured without increasing the size. <P>SOLUTION: In a pressure switch 1 having a body 2, a diaphragm 7, and a switch mechanism detecting a moving amount of the diaphragm 7, the switch mechanism includes: a support member 4 disposed in the body 2; a push block 5 contacting with the diaphragm 7 through an opening formed in the support member 4; a magnet 6 supported by the push block 5; a hollow spring receiving member 8 contacting with one end of a spring member 9 having the other end contacting with the push block 5; a hall element (magnetic detection means) 11; and a terminal base 10 having the hall element 11 and a substrate attachment part 10B supporting a substrate 12. The substrate attachment part 10B of the terminal base 10 is disposed penetrating through a hollow part of the spring receiving member 8. <P>COPYRIGHT: (C)2013,JPO&INPIT |
