## Abstract

Disclosed is a two-motion push-button switch which comprises first and second switch portions, each switch portion including a movable contact piece 4 or 6 formed of an elastic thin metal plate and having a reversing portion provided with a movable contact portion and arms formed to grip the reversing portion therebetween and fixed contact portions 2a,3a or 8a,9a formed in a case 1 or 7 at the position confronting said movable contact portion, and one slider 5 slidably arranged in the case, wherein the movable contact pieces are reversed by said slider to drive said two switch portions so that the reversing force of the moving contact piece of the first switch portion is made different from that of the movable contact piece of the second switch portion.

## Claims

### Claim 1

A push button switch comprising first and second switch portions mounted in a case; each switch portion including a respective movable contact piece formed of a resilient metal plate having a reversing portion adapted to change its position suddenly upon application of a pressing force different that the pressing force needed to change the position of the reversing portion of the other movable contact, a respective movable contact portion, and arms formed to hold the reversing portion therebetween; fixed contact portions formed in the case at a position confronting each respective movable contact portion, and means including a single slider engaging each of said contact pieces for applying said respective pressing forces to change the position of the respective reversing portions so that the first and second switch portions may be actuated at different times by a single actuation of said slider.

### Claim 2 (depends on 1)

A push-button switch as set forth in claim 1, wherein the movable contact piece comprises a pair of arms connected by a pair of bent portions and a reversing portion formed between the bent portions.

### Claim 3 (depends on 1)

A push-button switch as set forth in claim 1, wherein grooves are formed at positions confronting the slider and case and the arms of the movable contact pieces are engaged with said grooves, respectively.
