Claims

[Scope of utility model registration request]

(1) At least one pair of electrical contacts that are composed of a conductor and a contact fixed thereto and that open and close within the container; and a pair of electrical contacts that are arranged on both sides of the electrical contact and face each other. Each of the above-mentioned above-mentioned above-mentioned above-mentioned above-mentioned above-mentioned above-mentioned above-mentioned above-mentioned above-mentioned above-mentioned above-mentioned electric contact A switch characterized in that grooves are formed on each opposing surface of the compatible wall in correspondence with the locus drawn by the contact when the switch opens and closes.

(2) The switch according to claim 1, wherein each surface of the vertical wall is hardened by heat treatment.

(3) The above-mentioned vertical wall is formed by containing magnesia or zirconia as one of its compositions so that its surface crystallizes without vitrifying at high temperatures.Claim 1 or 2 of the Utility Model Registration Claim The switch mentioned.
