<p><P>PROBLEM TO BE SOLVED: To provide a pressure switch capable of finely adjusting an energizing force of a spring member by one kind of spring receiving member without increasing the number of components. <P>SOLUTION: A pressure switch 1 has: a body 2; a diaphragm 7; and a switch mechanism for switching output signals according to a travel amount of the diaphragm 7. The switch mechanism includes: a driving member 5 interlocked with a movement of the diaphragm 7; a Hall element (detection member) 11 for detecting the travel amount of the driving member 5; a spring member 9 contacting the driving member 5 on one end to energize the driving member 5; a spring receiving member 8 for receiving the other end of the spring member 9; and a substrate (output member) 12 for outputting signals according to the travel amount of the driving member 5 detected by the Hall element 11. Engagement step parts (energization force adjusting parts) 8a-8d for adjusting an energization force of the spring member 9 are provided on the spring receiving member 8. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
