Claims

[Claims for Utility Model Registration] (1) A cam plate fixed to the lever, a contact in contact with the cam plate, a spring that biases the contact towards the cam plate, and the contact. A lever switch having a guide that restricts movement of the cam plate only in the radial direction of the cam plate, the cam plate having a recess in which the contact can be seated at a neutral position on the cam surface, and An automatic return type lever switch formed such that the length from the shaft to the cam surface continuously increases as the distance from the neutral position of the cam surface increases. (2) The contact element is selected from a roller or a ball, the guide is formed of a cylindrical body that accommodates the contact element and the spring, and the cylindrical body is provided with a slit through which the cam plate passes. An automatic return lever switch according to Claim 1 of the Utility Model Registration Claim.
