Abstract
PURPOSE: To open and close plural switch contacts in turn by sliding a piston intermittently by changing the spring force intermittently against the pushing force of the piston by the detecting pressure as the piston moves.
CONSTITUTION: The piston 11 is inserted into the stepped hole 10a of the main body 10, and is held by the step 12 in the part of greater bore. The piston rod 13, which is extended to the outside of the main body, is in contact with the upper face of the piston 11, one end of the rod is pressed by the spring 14 attached to the main body. The other end of rod, which is in the outside of the main body, is connected to the contacts 15a, 15b. Also the spring bearing 17 is formed on the step 16 of the stepped hole 10a, the spring 18 is set to press the spring bearing 17 against the step 16. When a detected pressure P is introduced to the lower face of the piston and the piston is moved upward a fixed distance, the piston is made come in contact with the spring bearing 17, a pushing-down force that acts on the piston is applied to the spring 14 to add the spring force to the operation system.
