Claims

[Scope of utility model registration request]

A common contact provided on a case, first and second switching contacts provided on both sides of the common contact, an operating member provided on the case so as to be slidable in the arrangement direction of the respective contacts, and a common contact provided on the operating member. The coil is disposed in a space between a protruding pin which is pressed and biased toward the contact by a coil spring therein and the operating member of each of the contacts, and whose center portion is engaged with the tip of the protruding pin. When the central portion is biased toward the contact by a spring and is located between the common contact and the first switching contact or between the common contact and the second switching contact by operating the operating member, respectively. A changeover switch comprising a common contact and a movable piece that is obliquely pressed against the first or second changeover contact at the position.
