Claims

[Claims for Utility Model Registration] (1) It has a divisible case forming an opening, and the case is equipped with a plurality of electrical circuit opening/closing mechanisms each consisting of a fixed contact plate and a movable contact spring. A slide button capable of sliding linearly is installed in the opening of the case, and a cam is formed in conjunction with the slide button to apply biasing force to the contact spring to open and close the electrical circuit. An intermediate switch having the above features, wherein the case has a scale part that allows checking the open/closed state of the electric circuit, and an indicator is installed to indicate the scale part in conjunction with a slide button. (2) A splittable case that forms an opening is equipped with multiple electric circuit opening/closing mechanisms consisting of fixed contact plates and movable contact springs, which can be slid linearly into the opening of the case. A cam is provided that works in conjunction with the slide button to apply a biasing force to the contact spring to open and close the electrical circuit. An intermediate switch characterized by having a dustproof plate integrally formed with the button. (3) A splittable case forming an opening is equipped with multiple electric circuit opening/closing mechanisms consisting of fixed contact plates and movable contact springs, which can be slid linearly into the opening of the case. A slide button is installed, which works in conjunction with the slide button to form a cam that opens and closes the electrical circuit by applying a biasing force to the contact spring, and also prevents sparks generated when the electrical circuit opening/closing mechanism inside the case is operated to pass through the scale plate. An intermediate switch characterized by comprising a shielding plate integrally formed with the slide button to prevent the slide button from being damaged.
